A rule class, which contains the implementation of the rule. E.G. IssuableSubscriptionVisitor and BaseTreeVisitor. 。 如果依赖的是dcits-java-custom-rules开发,那么不需要进行任何修改。 3.3 Rule开发 以下以teller9的不允许 Then your logical choice may be to implement your own set of custom Java rules. 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. Otherwise, use an h2 for it. Before going further, be sure to have the adequate version of the SonarQube Java Plugin with your SonarQube instance. Exceptions To do so, get back to our test class MyFirstCustomCheckTest, and update the test() method as shown in the following code snippet (you may have to import class org.sonar.java.checks.verifier.JavaCheckVerifier): As you probably noticed, this test class contains a single test, the purpose of which is to verify the behavior of the rule we are going to implement. TRIVIAL Read more. Keeping this in consideration, how do you change rules in SonarQube? 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. This document is an introduction to custom rule writing for the SonarQube Java Analyzer. Somewhere around 70 or 80 characters is an ideal maximum, although this is not always achievable. For example, if you sample code used in your Unit Tests is having a dependency on Spring, add it there. Bug (Reliability domain) 3. The second things to to is to activate the rule within the plugin. 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. 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. The title of the rule should match the pattern "X should [ not ] Y" for most rules. An Android project can be analysed with the standard SonarQube Java plugin and this plugin just allows to import Android Lint reports if needed. 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). Go to the Rules page. 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. Among the 202 rules defined for Java by SonarQube, only 25 can be considered to have relatively low fault-proneness. The test should fail with error message "At least one issue expected", as shown in the code snippet below. More rules for Java and PHP developers SonarQube’s analyzers are continuously being improved, and this new version brings solid improvements for Java and PHP. Moreover, violations considered as "bugs" by SonarQube were generally not fault-prone and, consequently, the java,plugins,sonarqube Short answer is : with the currently available API you can't solve your third case. The rules you are going to develop will be delivered using a dedicated, custom plugin, relying on the SonarQube Java Plugin API. 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. If not, then check if you somehow missed a step. For instance, when browsing Java rules, you can see that there are 397 active guidelines that will be used when analysing your code: Once you get to know them, you can adjust the profile according to your needs. To register the rule, simply add the rule class to the list builder, as in the following code snippet: Because your rules are relying on the SonarJava API, you also need to tell the SonarJava parent plugin that some new rules have to be retrieved. The Code Analyzers we build are fueled by thousands of automated rules that we continuously maintain and improve. SonarQube is an open source static code analyzer, covering 27 programming languages. Starting with the subject, such as "Files", will ensure that all rules applying to files will be grouped together. The rules you are going to develop will be delivered using a dedicated, custom plugin, relying on the. Creative Commons Attribution-NonCommercial 3.0 United States License. The remediation action might lead to an impact on the overall design of the application. The method reportIssue(Tree tree, String message) from IssuableSubscriptionVisitor allows to report an issue on a given tree with a specific message. Before we start with the implementation of the rule itself, you need a little background. If the answer is "probably not" then it's a Bug. I am trying to find a way to get a list of all Sonarqube Java (or whatever) rules (with keys, description, etc.) Integrating SonarQube as a pull request approver on AWS CodeCommit. If a "See" heading exists in the rule, then the "See also" title should be at the h3 level. Place this jar file in the SONARQUBE_HOME/extensions/plugins directory. Because your rules are relying on the SonarSource Analyzer for Java API, you also need to tell the parent Java plugin that some new rules have to be retrieved. Vulnerabilities and hotspots should not overlap but can be related to the same subject. For the implementation of this rule, we chose to use an IssuableSubscriptionVisitor as the implementation basis of our rule. The Overflow Blog How to put machine learning models into production. Description / Features. This project already contains custom rules. In order to start working efficiently, we provide a empty template maven project, that you will fill in while following this tutorial. 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. Once your new rule is written, you can add it SonarQube: Login as an Quality Profile Administrator. It starts with a copy of the title. Because of that, you may want to specify, in your sample code used by your Unit Tests, the exact location, i.e. You implemented your first custom rule for the SonarQube Java Analyzer! Since our rule targets method declarations, we only need to visit methods. There are two ways to extend coding rules: If both are available, the Java API will be more fully-featured than what's available for XPath, and is generally preferable. Finding titles should be neutral, such as "Track x". Save these files somewhere in your storage. SonarQube Writing Custom Rules For Java - Implementing Custom Rule - Duration: 22:11.
