You implemented your first custom rule for the SonarQube Java Analyzer! (Languages where an error can cause program termination: COBOL, Python, PL/SQL, RPG.). Put a dependency on the API of the language plugin for which you are writing coding rules. It's also the property  which guarantees the compatibility with LTS 5.6. SonarSource's Java analysis has a great coverage of well-established quality standards. You can't modify an existing rule. An Android project can be analysed with the standard SonarQube Java plugin and this plugin just allows to import Android Lint reports if needed. // Compliant, This "switch" statement is useless and should be refactored or removed.

Keeping this in consideration, how do you change rules in SonarQube? 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 article, we're going to be looking at static source code analysis with SonarQube– which is an open-source platform for ensuring code quality. In SonarQube, rules are divided into three self-explaining categories: bugs, vulnerabilities and code smells. It is open-source, and available in SonarLint, SonarCloud and SonarQube. In the following example, we are expecting to have the issue being raised between the column 27 and 32 (i.e. E.G. 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. avoid using an additional message if the secondary location is likely to be on the same issue as the issue itself. However, we are not really done yet. The flag to be used is a simple "// Noncompliant" trailing comment on the line of code where an issue should be raised. Generate the SonarQube plugin (jar file). Let's start with a core question – why analyze source code in the first place? changing severity of certain rules for project. For most languages, an SSLR Toolkit is provided to help you navigate the AST. Code Quality and Security for Java . How to write a rule In my view (that may differs from the SonarSourcE/SonarQube developer view), SonarQube is provding two kind of rules : Other properties such as  and  can be freely modified. We're an open company, and our rules database is open as well! 3400+ Static Analysis Rules For other languages how to access a variable, for example, in XPath is less obvious, so we've provided tools. Because we chose a TDD approach, the first thing to do is to write examples of the code our rule will target. 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. They will be translated in the final output. 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. Fix vulnerabilities that compromise your app, and learn AppSec along the way with Security Hotspots. Somewhere around 70 or 80 characters is an ideal maximum, although this is not always achievable. From there, under the language section, select "Java", and then "MyCompany Custom Repository" under the repository section. Java. Up to now, our rule implementation only relied on the data provided directly by syntax tree that resulted from the parsing of the code. This class, on top of providing a bunch of useful methods to raise issues, also, . 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. 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. Sonarqube: What it is and Hi Julien My custom rule violation is not show in Eclipse. 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. In the test file MyFirstCustomCheck.java created earlier, copy-paste the following code: The test file now contains the following test cases: Once the test file is updated, let's update our test class to use it, and link the test to our (not yet implemented) rule. The complete list of rules, ), update the appropriate field on the References tab with the cited id. The JavaCheckVerifier reported that lines 5, 7 and 11 are raising unexpected issues, as visible in the stack-trace above. Moreover, violations considered as "bugs" by SonarQube were generally not fault-prone and, consequently, the Languages not listed here don't support custom rules. It inherits 236 active rules from default java profile “Sonar Way” Based on project need, changes can be made in the child profile. Very simply put, to ensure quality, reliability, and maintainability over the life-span of the project; a poorly written codebase is always more expensive to maintain. Select the Language for which you want to create the XPath rule. Features. If the 3 files described above are always the base of rule writing, there are situations where extra files may be needed. This plugin is a Java project analyzer, the way to use it is the same as SonarJava. Keeping this in consideration, how do you change rules in SonarQube? You'll see (at least for Java projects ) links for all rules engines and one that includes all of them. Everything is a plugin •SonarQube is an extensible platform •Language support provided as plugins •Additional rules also provided as plugins •Web UI can be extended by plugins •OpenEdge plugin available under an open-source That's why precisely configuring what to analyze for each project is a very important step. SonarQube (formerly Sonar) is an open source platform for continuous inspection of code quality. E.G. Since the rule should only raise an issue when these two types are the same, we then simply test if the return type is the same as the type of the first parameter using method is(String fullyQualifiedName), provided through the Type class, before raising the issue. 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. Save these files somewhere in your storage. The rules must be written in XPath (version 1.0) to navigate the language's Abstract Syntax Tree (AST). Why. Titles should be written in plural form if at all possible. 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. (out/err)" // Noncompliant, Parameters in an overriding virtual function should either use the same default arguments as the function they override, or not specify any default arguments // Noncompliant; waaaay too long, Files should not have too many lines of code, "System. Now its finally time to jump in to the implementation of our first rule! You can not deactivate a rule in built-in profile. Understanding the logic of a piece of code is required and it's up to the developer to define the remediation action. It is acceptable to omit this section when there are too many equally viable solutions. We again focused on rules that are valuable and commonly the subject of discussion in the C++ community. Security Hotspot (Security domain) For Code Smells and Bugs, zero false-positives are expected.

sonarqube rules for java

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). In the pom.xml, define in the Maven Dependency Plugin all the JARs you need to run your Unit Tests. Then your logical choice may be to implement your own set of custom Java rules. For the sake of the exercise, lets consider the following quote from a famous. 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. 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. These methods are used to register our rules with alongside the rule of the Java plugin. Before playing our rule against any real projects, we have to finalize its creation within the custom plugin, by registering it. Read more. There are two profiles available in the Java section. 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. MEDIUM To do so, simply add Kind.METHOD as a parameter of the returned immutable list, as shown in the following code snippet. Once your new rule is written, you can add it SonarQube: These are the guidelines that SonarSource uses internally to specify new rules. In our code ‘testService.java’, we have used a sample system.out .print ln( ) method. SonarQube is static code analyzer. Integrating SonarQube into a CI Making SonarQube part of a Continuous Integration process is possible. In this section we will write a custom rule from scratch. Likelihood: What is the probability the worst will happen? If you don't have a SonarQube platform installed on your machine, now is time to download its latest version from HERE! On Nov 25th, AWS CodeCommit launched a new feature that allows customers to configure approval rules on pull requests. Examples: remove unused imports, replace tabulations by spaces, remove call to System.out.println() used for debugging purpose, ... EASY "Classes should not have too many lines of code", There is no need to mark anything "Compliant" in the Compliant Solution; everything here is compliant by definition. Because we chose a TDD approach, the first thing to do is to write examples of the code our rule will target. For example, with the hotspot, Impact: Could the exploitation of the vulnerability result in significant damage to your assets or your users? Because of that, you may want to specify, in your sample code used by your Unit Tests, the exact location, i.e. Bug (Reliability domain) 3. java,plugins,sonarqube Short answer is : with the currently available API you can't solve your third case. I am trying to find a way to get a list of all Sonarqube Java (or whatever) rules (with keys, description, etc.) in between which 2 specific Columns, where you are expecting the issue to be raised. For example, if the highlighted missing protection (such as secure cookie flag) helps protect a bit against MITM attacks, list all mandatory protections that, at the contrary, greatly lower this risk (such as encryption). It is not recommended to drive the review with. Why list references to other rules under "see also" instead of "see"? The second things to to is to activate the rule within the plugin. Note that the "should [ not ]" pattern is too strong for Finding rules, which are about observations on the code. 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. 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. Generate the SonarQube plugin (jar file). 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. It helped us to standardize our coding standards and write clean code, making sure no code with code smells goes to production. You have to add a @RuleProperty to your Rule. … SonarQube v8.3 extends XSS injection flaw detection to several common frameworks. Each of these constructions is associated with a specific Kind as well as an interface explicitly describing all its particularities. add the relevant standard-related tag/label such as cwe, misra, etc. Bugs See rules. Hence, at the time being, you will need to install it manually: Obtain the RIPS plugin file (see table above). The RIPS SonarQube plugin lets you run scans from SonarQube and imports issues from the corresponding RIPS scans to SonarQube. Move the plugin file to /extensions/plugins/.
