sonarqube中的ClassCastException自定義java檢查

您好我正在編寫自己的sonarqube版本6.1的插件，使用版本4.0中的java-plugin的檢查。更具體地說，我試圖擴展類SubscriptionVisitor以獲得有關Java文件爬行的幫助。但是，我遇到了這個問題：sonarqube中的ClassCastException自定義java檢查

Caused by: java.lang.ClassCastException: org.sonar.java.model.declaration.MethodTreeImpl cannot be cast to org.sonar.java.model.JavaTree

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

MethodTreeImpl無疑延伸了JavaTree類。我假設問題將在不同的類加載器中。有人可以幫我嗎？

事實上，這很可能是關於不同的ClassLoaders，因此您能否解釋一下如何打包自定義插件？如果Maven的基礎 - 提供pom.xml – Godin

你應該聲明對org.sonarsource.java:sonar-java-plugin及其作爲provided組件的依賴。這在examples of custom rules中顯示。否則，它們將被打包到你的插件中，這就是爲什麼不同的類加載器加載了相同的類。
