こんにちは私はバージョン4.0のjava-pluginからのチェックを使用してsonarqubeバージョン6.1用の独自のプラグインを作成しています。より具体的には、Javaファイルクロールのヘルプを得るためにSubscriptionVisitorクラスを拡張しようとしています。しかし、私はこの問題に遭遇しました：ClassCastException in sonarqube custom java check
Caused by: java.lang.ClassCastException: org.sonar.java.model.declaration.MethodTreeImpl cannot be cast to org.sonar.java.model.JavaTree

MethodTreeImplは明らかにJavaTreeクラスを拡張します。問題は別のクラスローダーにあると仮定します。 誰でも助けてくれますか？ここで

これはおそらく、これは異なるClassLoadersに関するものです。したがって、カスタムプラグインをパッケージ化する方法を説明してください。 Mavenベースの場合 - pom.xmlを提供 – Godin
