sonarqube自定义java检查中的ClassCastException

嗨，我正在为sonarqube版本6.1编写自己的插件，使用版本4.0中java插件的检查。更具体地说，我正在尝试扩展类SubscriptionVisitor以获得Java文件爬网方面的帮助。但我遇到了这个问题：

Caused by: java.lang.ClassCastException: org.sonar.java.model.declaration.MethodTreeImpl cannot be cast to org.sonar.java.model.JavaTree
at org.sonar.java.ast.visitors.SubscriptionVisitor.visitChildren(SubscriptionVisitor.java:116)
at org.sonar.java.ast.visitors.SubscriptionVisitor.visit(SubscriptionVisitor.java:97)

at org.sonar.java.model.VisitorsBridge.visitFile(VisitorsBridge.java:123)
at org.sonar.java.ast.JavaAstScanner.simpleScan(JavaAstScanner.java:84)

MethodTreeImpl显然扩展了JavaTree类。我假设问题将出现在不同的类加载器中。 有人能帮我吗

您应该声明对

org.sonarsource.java:sonarjava插件及其组件的依赖关系为
提供的
。如图所示。否则，它们将被打包到您的插件中，这就是为什么相同的类由不同的类加载器加载。
事实上，这很可能是关于不同的类加载器，因此您能否解释一下如何打包自定义插件？如果基于Maven-请提供pom.xml
