sonarqube rules for java

Do not give examples that make references to real companies or organizations: When a reference is made to a standards specification, e.g. RIPS Plugin Setup The RIPS plugin for SonarQube is currently not in the SonarQube plugin repository. and export it as an Excel, csv or xml. This can be achieved using the special keywords 'sc' (start-column) and 'ec' (end-column) in the "Noncompliant" comment. We're an open company, and our rules database is open as well! To do so, simply add, Once the nodes to visit are specified, we have to implement how the rule will react when encountering method declarations. Features. As its name is telling us, it is based on a subscription mechanism, allowing to specify on what kind of tree the rule should react. Using generic exceptions such as Error, RuntimeException, Throwable, and Exception prevents calling methods from handling true, system-generated exceptions differently than application-generated errors. Hi Julien My custom rule violation is not show in Eclipse. SonarQube (formerly Sonar) is an open source platform for continuous inspection of code quality. Finally, be sure that this registrar class is also correctly added as an extension for your custom plugin, by adding it to your Plugin definition class (MyJavaRulesPlugin.java). Usage. In answering, you should factor in Murphy's Law without predicting Armageddon. Generate the SonarQube plugin (jar file). Available in all SonarQube Editions! The flag to be used is a simple ", " trailing comment on the line of code where an issue should be raised. 3400+ Static Analysis Rules SonarQube is an open-source platform developed for continuous inspection of code quality. However, the SonarAnalyzer for Java provides a lot more regarding the code being analyzed, because it also construct a semantic model of the code. You need to download the sslr-{language}-toolkit-{version}.jar file corresponding to the version of your language plugin you have on your SonarQube instance. The BaseTreeVisitor contains a visit() method dedicated for each and every kind of the syntax tree, and is particularly useful when the visit of a file has to be fine tuned. and export it as an Excel, csv or xml. (Languages where an error can cause program termination: COBOL, Python, PL/SQL, RPG.). add any related tags such as security, bug, etc. For the implementation of this rule, we chose to use an IssuableSubscriptionVisitor as the implementation basis of our rule. ForbiddenCallRuleTest.java, IssueOnEachFileRuleTest.java TrivialEvaluateRuleTest.java are the unit tests for the custom rules. Improve database performance with connection pooling. By looking back at our test file, it's easy to figure out that raising an issue line 5 is wrong because the return type of the method is void, line 7 is wrong because Object is not the same as int, and line 11 is also wrong because of the variable arity of the method. From there, under the language section, select "Java", and then "MyCompany Custom Repository" under the repository section. The test should fail with error message "At least one issue expected", as shown in the code snippet below. don't write a novel. Raising these issues is however correct accordingly to our implementation, as we didn't check for the types of the parameter and return type. In the following example, we are expecting to have the issue being raised between the column 27 and 32 (i.e. Information about the analysis of Java features is available here. In SonarQube, analyzers contribute rules which are executed on source code to generate issues. Somewhere around 70 or 80 characters is an ideal maximum, although this is not always achievable. This time, we will need to use the semantic API! Keeping code clean, simple, and easy to read is also a lot easier with SonarQube. As a first step, we can consequently safely cast the tree directly into a MethodTree, as shown below. Before going further, be sure to have the adequate version of the SonarQube Java Plugin with your SonarQube instance. It helps in improving code quality by providing various metrics for bugs, vulnerabilities, security, code coverage, etc. It is also possible to use external files to describe rule metadata, such as a description in html format. TRIVIAL Supported Frameworks and Language Standards Here's the AST for our sample: The XPath language provides a way to write coding rules by navigating this AST, and the SSLR Toolkit for the language will give you the ability to test your new rules against your sample code. The latest version of SSLR Toolkit can be downloaded from following locations: For an SSLR preview, consider the following source code sample: While parsing source code, SonarQube builds an Abstract Syntax Tree (AST) for it, and the SSLR Toolkit provided for each language will show you SonarQube's AST for a given piece of code. In this file, we consider numerous cases that our rule may encounter during an analysis, and flag the lines which will require our implementation to raise issues. Siva Reddy 2,590 views 16:18 The Art of Code - Dylan Beattie - … created earlier, copy-paste the following code: line 2: A constructor, to differentiate the case from a method; line 4: A method without parameter (foo1); line 6: A method returning the same type as its parameter (foo3), which will be noncompliant; line 7: A method with a single parameter, but a different return type (foo4); with a single parameter and same return type, but with non-primitive types (foo5), therefore non compliant too; line 10: A method with more than 1 parameter (foo6); line 11: A method with a variable arity argument (foo7); proceed to the next step of TDD: make the test fail! SonarQube provides a quick and easy way to add new coding rules directly via the web interface for certain languages using XPath 1.0 expressions. At the end of the review, the developer should be sure that in its context the implementation of this protection improves the overall application's security. Each of these constructions is associated with a specific Kind as well as an interface explicitly describing all its particularities. Otherwise, use an h2 for it. SonarQube's Java static code analysis detects Bugs, Security Vulnerabilties, Security Hotspots, and Code Smells in Java code for better Reliability, Security, and Maintainability SonarQube is an open source static code analyzer, covering 27 programming languages. Likelihood: What is the probability the worst will happen? It is acceptable to omit this section when there are too many equally viable solutions. Check this example : How to Test Sources requiring External Binaries, {"serverDuration": 217, "requestCorrelationId": "a48b1aeb21328fea"}, Creative Commons Attribution-NonCommercial 3.0 United States License, https://github.com/SonarSource/sonar-custom-rules-examples/tree/master/java-custom-rules, rules already implemented in the Java Plugin, https://github.com/SonarSource/sonar-custom-rules-examples/blob/master/java-custom-rules/src/main/java/org/sonar/samples/java/checks/SecurityAnnotationMandatoryRule.java, https://github.com/SonarSource/sonar-custom-rules-examples/blob/master/java-custom-rules/pom.xml#L147, https://github.com/SonarSource/sonar-java, https://github.com/SonarSource/sonar-custom-plugin-example, A test file, which contains Java code used as input data for testing the rule, A test class, which contains the rule's unit test. Bug (Reliability domain) 3. MEDIUM 14 new rules dedicated to users of the Spring Frameworks, adding to 400+ static analysis rules… Security Hotspot rules d… Exceptions SonarQube Writing Custom Rules For Java - Implementing Custom Rule - Duration: 22:11. When encountering a method returning the same type as its parameter, the issue will now raise issue, as visible in the following picture: You have to add a @RuleProperty to your Rule. Once we know that our method has a single parameter, let's start by getting the symbol of the method using the symbol() method from the MethodTree. For example, if you sample code used in your Unit Tests is having a dependency on Spring, add it there. method. Languages not listed here don't support custom rules. For Vulnerabilities, the target is to have more than 80% of issues be true-positives. Then your logical choice may be to implement your own set of custom Java rules. Hotspot - An optional protection is missing and the developer needs to do a review before deciding whether to apply a fix. In the previous steps, we modified the implementation of the method to return an empty list, therefore not subscribing to any node of the syntax tree. Since our check is not yet implemented, no issue can be raised yet, so that's the expected behavior. method complexity should be raised on the method signature, method count in a class should be raised on the class declaration. Test passed? With a parameter of: The lines in these code samples where issues are expected should be marked with a "Noncompliant" comment, "Compliant" comments may be used to help demonstrate the difference between what is and is not allowed by the rule, It is acceptable to omit this section when demonstrating noncompliance would take too long, e.g. In this file, we consider numerous cases that our rule may encounter during an analysis, and flag the lines which will require our implementation to raise issues. This capability is available in Eclipse, IntelliJ and VSCode for developers (SonarLint) as well as throughout the development chain for automated code review with self-hosted SonarQube or cloud-based SonarCloud. For any given rule, highlighting behavior should be consistent across languages within the bounds of what's relevant for each language. In package org.sonar.samples.java.checks of /src/main/java, create a new class called MyFirstCustomCheck extending class org.sonar.plugins.java.api.IssuableSubscriptionVisitor provided by the Java Plugin API. To do so, we will use a Test Driven Development (TDD) approach, relying on writing some test cases first, followed by the implementation a solution. Knowing the XPath language is the only prerequisite, and there are a lot of tutorials on XPath online. Gandalf - Why Program When Magic Rulez (WPWMR, p.42), “For a method having a single parameter, the types of its return value and its parameter should never be the same.”. Go to the Rules page. To do so, simply add Kind.METHOD as a parameter of the returned immutable list, as shown in the following code snippet. Recently we started using SonarQube for code quality, security checks and code coverage reports for our projects. For example: the rule "Parameters should be final" will raise an issue on the method name, and highlight each non-final parameter. The complete list of rules, what is the time to fix the issue? Prior to running any rule, the SonarQube Java Analyzer parses a given Java code file and produces an equivalent data structure: the, Each construction of the Java language can be represented with a specific kind of Syntax Tree, detailing each of its particularities. Then, replace the content of the nodesToVisit() method with the content from the following code snippet (you may have to import com.google.common.collect.ImmutableList). The main differences between vulnerabilities and hotspots are explained on the security-hotspots page. Of course, before going any further, we need a key element in rule writhing, a specification! Because the flagged lines do not comply with the rule. ls sonarqube_extensions/plugins/ sonar-java-plugin-5.14.0.18788.jar 以降はこの sonarqube_extensions/plugins ディレクトリにプラグインのjarファイルが残っている限りは個別のインストールは不要になります。 If the 3 files described above are always the base of rule writing, there are situations where extra files may be needed. It's also the property  which guarantees the compatibility with LTS 5.6. However, this approach is not always the most optimal one. The following parts are mandatory in RSPEC language-specification: Guidelines regarding COBOL, keywords and code are the same as for other rules. Everything worked well with SonarQube for all our … Now its finally time to jump in to the implementation of our first rule! For most languages, an SSLR Toolkit is provided to help you navigate the AST. If not, then check if you somehow missed a step. exactly on "Order" variable type): SonarQube Platform: http://www.sonarqube.org/, SonarQube Java Plugin Github repository: https://github.com/SonarSource/sonar-java, SonarQube Java Custom Rules Example: https://github.com/SonarSource/sonar-custom-plugin-example. This visitor offers an easy approach to writing quick and simple rules, because it allows us to narrow the focus of our rule to a given set of Kinds to visit by subscribing to them. The Code Analyzers we build are fueled by thousands of automated rules that we continuously maintain and improve. This semantic model provides information related to each symbol being manipulated. ), update the appropriate field on the References tab with the cited id. This plugin is a Java project analyzer, the way to use it is the same as SonarJava. For a method, for instance, the semantic API will provide useful data such as a method's owner, its usages, the types of its parameters and its return type, the exception it may throw, etc. To do so, simply execute the test from the test file using JUnit. Covering all the possible cases is not necessarily required, the goal of this file is to cover all the situations which may be encountered during an analysis, but also to abstract irrelevant details. add the relevant standard-related tag/label such as cwe, misra, etc. Create as many custom rules as required. The Java plugin is used to monitor the quality of Java within SonarQube. The following screenshot shows how severity of a rule can be changed to info from minor. The list of node types to cover is specified through the. Go to Quality Profiles in SonarQube. Consequently, as we will rely on version 4.5.0.8398 of the Java plugin, the SonarQube instance which will use the custom plugin will need version 4.5.0.8398 of the Java Plugin as well. When in doubt, ask yourself: "Is code that breaks this rule doing what the programmer probably intended?" Titles should be as concise as possible. Today, we are going to learn how to setup SonarQube on our machine to run SonarQube scanner on Place this jar file in the SONARQUBE_HOME/extensions/plugins directory. Examples: Too many nested IF statements, Methods should not have too many parameters, UNION should not be used in SQL SELECT statements, Public java method should have a javadoc, Avoid using deprecated methods, ... HIGH (If you forget, the overnight automation will remember for you. Titles should be written in plural form if at all possible. To do so, override method, Registering the rule in the custom plugin. SonarQube takes project code as the input, analyzes it using pre-defined coding rules and publishes web based results giving overview of technical quality of code. A custom plugin is a Maven project, and before diving into code, it is important to notice a few relevant lines related to the configuration of your soon-to-be-released custom plugin. ... Thousands of automated Static Code Analysis rules, protecting your app on multiple fronts, and guiding your team. Select the Language for which you want to create the XPath rule. Ideally, the examples should depend upon the default values of any parameters the rule has, and these default values should be mentioned before the code block. This class, on top of providing a bunch of useful methods to raise issues, also, . You'll see (at least for Java projects ) links for all rules engines and one that includes all of them. Understanding the logic of a piece of code is required before doing a little and easy refactoring (1 or 2 lines of code), but understanding the big picture is not required. In SonarQube, rules are divided into three self-explaining categories: bugs, vulnerabilities and code smells. This project already contains custom rules. In the pom.xml, define in the Maven Dependency Plugin all the JARs you need to run your Unit Tests. There are two profiles available in the Java section. Because we chose a TDD approach, the first thing to do is to write examples of the code our rule will target. For the moment, don't touch these two properties. Once the nodes to visit are specified, we have to implement how the rule will react when encountering method declarations. You can raise an issue on a given line, but you can also raise it at a specific Token. For the sake of the exercise, lets consider the following quote from a famous Guru as being the specification of our custom rule, as it is of course absolutely correct and incontrovertible. To perform secure cryptography, operation modes and padding scheme are essentials and should be used correctly according to the encryption algorithm: Shows how to bootstrap a project to write custom rules for Java, JS, PHP, Python, Cobol, RPG Because we registered the rule to visit Method nodes, we know that every time the method is called, the tree parameter will be a org.sonar.plugins.java.api.tree.MethodTree (the interface tree associated with the METHOD kind). File should not have too many lines of code // Noncompliant; singular form used, Avoid file with too many lines of code // Noncompliant; doesn't follow "x should [not] y" pattern, Don't use "System. It provides lot of rules to scan multiple languages of your projects It provides a way to scan all the languages together which are present in one git repo. Example: sonar.java.source=1.6. The hotspot-review should be done by developers by themselves without external help: Recommended Secure Coding Practices - describing all the ways to mitigate the risk. The rules you are going to develop will be delivered using a dedicated, custom plugin, relying on the SonarQube Java Plugin API. The rules you are going to develop will be delivered using a dedicated, custom plugin, relying on the. Pull requests which fail to satisfy the required approvals cannot be merged into your important branches. Features 500+ rules (including 100+ bug detection rules and 300 Vulnerabilities and hotspots should not overlap but can be related to the same subject. Industry strength code needs to statically & dynamically capture code quality.Also, more and more organizations are using “production quality” home assignments to shortlist candidates for job interviews.So, it really pays to set up code quality tools like SonarQube on your home development environment to get feedback on your code quality with the view to learm & improve. An Android project can be analysed with the standard SonarQube Java plugin and this plugin just allows to import Android Lint reports if needed. This document is an introduction to custom rule writing for the SonarQube Java Analyzer. In the code snippet below, note the plugin API version () provided through the properties. Don't take over the interface with a narrative. Note that rules registered in GetJavaChecks() will only be played against source files, while rules registered in GetJavaTestChecks() will only be played against test files. // Noncompliant, Every "switch" statement shall have at least one case-clause. MISRA, the following steps must also be taken: If needed, references to other rules should be listed under a "See also" heading. // Compliant, This "switch" statement is useless and should be refactored or removed. Prior to running any rule, the SonarQube Java Analyzer parses a given Java code file and produces an equivalent data structure: the Syntax Tree. There should be no category/tag prefixed to the rule title, such as "Accessibility - Image tags should have an alternate text attribute". It starts with a copy of the title. Code quality analysis mainly relies on a set of tools that look at your code and give you hints. Your rule should now be visible (with all the other sample rules). Put a dependency on the API of the language plugin for which you are writing coding rules. Keeping this in consideration, how do you change rules in SonarQube? Results summarize the status on project level which can be informative to management and is also possible to go on the issue level to see specific line of code causing the rule violation. highlight the minimum code to show the line's contribution to the issue. Go to the Rules page. The flag to be used is a simple "// Noncompliant" trailing comment on the line of code where an issue should be raised. I have updated sonar products to versions mentioned in items involved in MMF-248. In such a situation, it could be useful to take a look at another visitor provided with the API: org.sonar.plugins.java.api.tree.BaseTreeVisitor. In this section we will write a custom rule from scratch. No need to understand the logic but potential impacts. When possible, each issue should be raised on the line of code that needs correction, with highlighting limited to the portion of the line to be corrected. Java Internationalization (I18n) Rules for SonarQube Installation. Browse other questions tagged java sonarqube rules or ask your own question. SonarQube performs automatic reviews with static analysis of code to detect bugs, code smells (i.e., any characteristic in the source code that could indicate a deeper problem), and security vulnerabilities on 20+ programming languages. If a "See" heading exists in the rule, then the "See also" title should be at the h3 level. If you have a fresh install or do not possess the same version, install the adequate version of the Java Plugin. Note that latest released versions of the Java Analyzer are always compatible with the current LTS version of SonarQube. Security Hotspot (Security domain) For Code Smells and Bugs, zero false-positives are expected. in between which 2 specific Columns, where you are expecting the issue to be raised. Why list references to other rules under "see also" instead of "see"? Before implementing a new coding rule, you should consider whether it is specific to your own context or might benefit others. Evaluate Confluence today. Any piece of code in the rule title should be double-quoted (and not single-quoted). SonarQube empowers all developers to write cleaner and safer code. Bugs See rules. Prior to running any rule, the SonarQube Java Analyzer parses a given Java code file and produces an equivalent data structure: the Syntax Tree. The "is security sensitive" part can be replaced with "can lead to ... Those questions should help the developer to decide whether or not a missing protection has to be implemented based on the context of the application. It will cover all the main concepts of static analysis required to understand and develop effective rules, relying on the API provided by the SonarQube Java Plugin. since it is an actual sentence, unless it ends with a regular expression, in which case the regular expression should be preceded by a colon and should end the message. changing severity of certain rules for project. Note that if we had registered multiple node types, we would have to test the node kind before casting by using the method Tree.is(Kind ... kind). These methods are used to register our rules with alongside the rule of the Java plugin. SonarQube is a universal tool for static code analysis that has become more or less the industry standard. Rules 540+. Remove or refactor this useless "switch" statement. Put a dependency on the API of the language plugin for which you are writing coding rules. From the symbol, it is then pretty easy to retrieve the type of its first parameter, as well as the return type (You may have to import org.sonar.plugins.java.api.semantic.Symbol.MethodSymbol and org.sonar.plugins.java.api.semantic.Type). com.ashish.custom.sonar.java.plugin.RulesList This class lists all custom rules and provides the list to the CustomJavaFileCheckRegistrar class to register them with sonarqube 6 com.ashish.custom.sonar.java.rules In this class, you will notice methods GetJavaChecks() and GetJavaTestChecks(). SonarQube Writing Custom Rules For Java - Environment Setup - Duration: 16:18. The most famous tools are Findbugs, PMD, Checkstyle; but also code coverage tools such as JaCoCo. At least this is the target so that developers don't have to wonder if a fix is required. Go back to the, method. If it might benefit others, you can propose it on the Community Forum. Since all locations are likely to be on the same line, additional messages would only confuse the issue. If you're writing rules for XML, skip down to the Adding your rule to the server section once you've got your rules written. Rule Set Information Accepted formats are: "1.X" (for instance 1.6 for java 6, 1.7 for java 7, 1.8 for java 8, etc.) The difficulty of exploiting a weakness should not be a criterion for specifying a hotspot or a vulnerability. It is activated for project “Sample project for SonarQube”. This part can be easily translated by a developer into examples of implementation/source code, if the recommendations are too abstract the developer will not be able to imagine the fix and decide whether to implement it. Import of test coverage reports; Custom rules; Useful links For example, with the hotspot, Impact: Could the exploitation of the vulnerability result in significant damage to your assets or your users? This section ends with "There is a risk if you answered yes to any of those questions.". The Overflow Blog How to put machine learning models into production. Tick the Template criterion and select For XML, which is already immediately accessible to XPath, you can simply write your rules and check them using any of the freely available tools for examining XPath on XML. For most rules, the SQALE remediation cost is constant per issue. JSP and Spring are covered for Java; Razor and ASP.NET Core MVC are added for C#. (If you forget, the overnight automation will remember for you.). Note that this sample file does not need to be compilable, but it should be structurally correct. All the 202 rules available in SonarQube for Java were found in the analyzed projects. Automatically detect Bugs, Vulnerabilities and Code Smells with SonarSource's Javascript analysis. For descriptions written in JIRA, this means using double curly braces ({{ and }}) to enclose such text. The remediation action might lead to locally impact the design of the application. Once your new rule is written, you can add it SonarQube: Login as an Quality Profile Administrator. On Nov 25th, AWS CodeCommit launched a new feature that allows customers to configure approval rules on pull requests. See : https://github.com/SonarSource/sonar-custom-rules-examples/blob/master/java-custom-rules/pom.xml#L147. Place this jar file in the SONARQUBE_HOME/extensions/plugins directory. Don't hesitate to explore the semantic package of the API in order to have an idea of what kind of information you will have access to during analysis! Moreover, if an issue is triggered because a number was above a threshold value, then both the number and the threshold value should be mentioned in the issue message. With SonarQube installed and configured and the administrative console up and active, the tool is ready to begin inspecting source code and reporting on a variety of SonarQube metrics. It is not recommended to highlight a widely-used technology (weak in some contexts) when its replacement can only be done with such significant changes (eg: a new authentication system or a different database engine) that it would block developers who may not be responsible for the architecture of the application. java, enterprise-integration, architecture, sonarqube,.net, php, static code analysis, code analyzer Published at DZone with permission of Ajitesh Kumar , DZone MVB . If you are using the template custom plugin as a base of this tutorial, you should have everything done already, but feel free to have a look at the MyJavaFileCheckRegistrar.java class, which connects the dots. Login as an Quality Profile Administrator, Select the Language for which you want to create the XPath rule, Tick the Template criterion and select "Show Templates Only", Click on it to select it, then use the interface controls to create a new instance. Once you have your answer, it's time to assess whether the Impact and Likelihood of the Worst Thing are High or Low. Sonarqube: What it is and The title of the rule should match the pattern "X should [ not ] Y" for most rules. For potential-bug rules, it should make it explicit that a manual review is required. Now that you've fleshed out the description, you should have a fairly clear idea of what type of rule this is, but to be explicit: Bug - Something that's wrong or potentially wrong. In this case, we chose to report the issue at a precise location, which will be the name of the method. It should be in the imperative mood ("Do x"), and therefore start with a verb. Now, let's proceed to the next step of TDD: make the test fail! Starting with the subject, such as "Files", will ensure that all rules applying to files will be grouped together. It means less maintenance for you, and benefit to others. If SonarQube's results aren't relevant, no one will want to use it. You can not deactivate a rule in built-in profile. Code Smell - Something that will confuse a maintainer or cause her to stumble in her reading of the code. It provides a server component with a bug dashboard which allows to view and analyze reported problems in your source code. To put machine learning models into production, number of lines etc ).
