sonar如何添加自定义JAVA规则

参考：

1、https://segmentfault.com/a/1190000008659108

2、https://docs.sonarqube.org/display/DEV/Adding+Coding+Rules

3、https://docs.sonarqube.org/display/DEV/Adding+Coding+Rules+using+Java

4、https://docs.sonarqube.org/display/PLUG/Writing+Custom+Java+Rules+101

有两种方式可以扩展代码规则：但是Java只支持方式1

1、Writing coding rules using Java via a SonarQube plugin

2、Adding XPath rules directly through the SonarQube web interface

Writing coding rules in Java is a six-step process:

• Create a SonarQube plugin.
• Put a dependency on the API of the language plugin for which you are writing coding rules.
• Create as many custom rules as required
• Generate the SonarQube plugin (jar file)
• Place this jar file in the SONARQUBE_HOME/extensions/plugins directory
• Restart SonarQube server

下面详述这个过程：

1、把项目拉到本地

git clone git@github.com:shengulong/sonar-custom-rules-examples.git

2、里面有cobol/java/javascript/php/rpg的自定义规则，我们只关注java的

3、使用intellij idea打开项目java-custom-rules（github上，我已经调试通过）。这是一个maven项目的模板。

4、修改下pom文件:sonar的版本以及对应的java插件版本，这样sonar6.0以上版本都可以用这个插件

 <properties>
         <!--<sonar.version>6.3</sonar.version>-->
         <sonar.version>6.0</sonar.version>
         <!-- this 6.3 is only required to be compliant with SonarLint and it is required
             even if you just want to be compliant with SonarQube 5.6 -->
         <!--<java.plugin.version>4.7.1.9272</java.plugin.version>-->
         <java.plugin.version>4.5.0.8398</java.plugin.version>
         <sslr.version>1.21</sslr.version>
         <gson.version>2.6.2</gson.version>
 </properties>

5、修改下文件，因为最初下载的报编译错误

sonar-custom-rules-examples/java-custom-rules/src/main/java/org/sonar/samples/java/MyJavaRulesDefinition.java

 

a、注释掉//import org.sonar.plugins.java.Java;

b、修改函数，主要修改成下文的java字段，因为我们编辑的java规则插件

 @Override
   public void define(Context context) {
     NewRepository repository = context
       .createRepository(REPOSITORY_KEY, "java")
       .setName("MyCompany Custom Repository");

     List<Class> checks = RulesList.getChecks();
     new RulesDefinitionAnnotationLoader().load(repository, Iterables.toArray(checks, Class.class));

     for (Class ruleClass : checks) {
       newRule(ruleClass, repository);
     }
     repository.done();
   }

6、其他修改参照github代码提交记录，然后按照https://docs.sonarqube.org/display/PLUG/Writing+Custom+Java+Rules+101的步骤操作即可，来张最终效果图：
