Sonar并不是简单地把不同的代码检查工具结果（例如 FindBugs，PMD 等）直接显示在 Web 页面上，而是通过不同的插件对这些结果进行再加工处理，通过量化的方式度量代码质量的变化，从而可以方便地对不同规模和种类的工程进行代码质量管理。
sonarqubue默认的对java的检测规则不一定适合我们，可以自己去自定义rules。
禁用rules
Rules-Quality Profile- Sonar way Java
查看激活的规则，可以禁用，或者更改严重级别(Severity)
自定义rules
sonar提供XPath或Java方式的扩展，有的语言支持XPath，有的只能支持Java，比如Java语言只支持Java方式的扩展。具体详见Support of Custom Rules by Language
步骤如下：
创建一个SonarQube插件
增加相关依赖
创建自定义rules
生成插件的jar包
将该jar包放在SONARQUBE_HOME/extensions/plugins目录下
重启SonarQube
添加maven依赖

编写plugin
创建plugin入口
public class MySonarPlugin implements Plugin {
public void define(Context context) {
// server extensions -> objects are instantiated during server startup
context.addExtension(MyJavaRulesDefinition.class);
// batch extensions -> objects are instantiated during code analysis
context.addExtension(MyJavaFileCheckRegistrar.class);
}
}这个类实现了org.sonar.api.Plugin接口，主要添加两类扩展：
server extensions
在sonarqube server启动时实例化，实现org.sonar.api.server.rule.RulesDefinition接口
public class MyJavaRulesDefinition implements RulesDefinition {
public static final String REPOSITORY_KEY = "myRepo";
public void define(Context context) {
NewRepository repository = context.createRepository(REPOSITORY_KEY, Java.KEY);
repository.setName("my sonar repo");
AnnotationBasedRulesDefinition.load(repository, "java", RulesList.getChecks());
repository.done();
}
}
public class RulesList {
private RulesList() {
}
public static List<Class> getChecks() {
return ImmutableList.<Class>builder().addAll(getJavaChecks()).addAll(getJavaTestChecks()).build();
}
public static List<Class<? extends JavaCheck>> getJavaChecks() {
return ImmutableList.<Class<? extends JavaCheck>>builder()
.add(AvoidSmallerLengthVariableNameRule.class)
.build();
}
public static List<Class<? extends JavaCheck>> getJavaTestChecks() {
return ImmutableList.<Class<? extends JavaCheck>>builder()
.build();
}
}
batch extensions
在分析代码的时候实例化，实现org.sonar.plugins.java.api.CheckRegistrar接口
public class MyJavaFileCheckRegistrar implements CheckRegistrar {
public void register(RegistrarContext registrarContext) {
// Call to registerClassesForRepository to associate the classes with the correct repository key
registrarContext.registerClassesForRepository(MyJavaRulesDefinition.REPOSITORY_KEY,
Arrays.asList(checkClasses()), Arrays.asList(testCheckClasses()));
}
/**
* Lists all the checks provided by the plugin
*/
public static Class<? extends JavaCheck>[] checkClasses() {
return new Class[] { // List of rules to be included here
AvoidSmallerLengthVariableNameRule.class
};
}
/**
* Lists all the test checks provided by the plugin
*/
public static Class<? extends JavaCheck>[] testCheckClasses() {
return new Class[] {};
}
}创建规则

private static final String DEFAULT_VALUE = "SmallerLengthLocalVariable";
private JavaFileScannerContext context;

@RuleProperty(
defaultValue = DEFAULT_VALUE,

protected String name;
public void scanFile(JavaFileScannerContext context) {
this.context = context;
scan(context.getTree());
}
@Override
public void visitVariable(VariableTree tree) {
String variableName = tree.simpleName().name();
System.out.println("Scanning the variable : " + variableName);
if(variableName.length() < 4) {
context.reportIssue(this,tree, "Variable length is less than 4 characters");
}
super.visitVariable(tree);
}
