SonarQube 5.2的自定义插件产生NoClassDefFoundError
我正在尝试为SonarQube 5.2开发插件，但是，当我部署插件时，SonarQube服务器无法启动。 该日志显示了带有Google Guava类的NoClassDefFoundexception：
Caused by: java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableList at br.gov.tcu.plugins.pmd.PmdTcuPlugin.getExtensions(PmdTcuPlugin.java:48) ~[na:na] at org.sonar.server.plugins.ServerExtensionInstaller.installExtensions(ServerExtensionInstaller.java:55) ~[sonar-server-5.2.jar:na] ... 15 common frames omitted 当我运行mvn dependency:tree ，日志显示实际上包含了Guava，但在打包插件后，它不包含Guava jar：

我的pom看起来像这样：

你可以看到我试图删除旧版本的sonar-plugin-api，但它仍然无法正常工作。
我在这里想念的是什么？
谢谢！
我在这里找到了这个问题。 问题出在sonar-xml-plugin的依赖层次结构中。 我不仅要排除较旧的sonar-plugin-api ，还要排除sonar-colorizer依赖。
所以，为了解决这个问题，我只需将该依赖项更改为：
org.sonarsource.xml sonar-xml-plugin sonar-plugin 1.4 provided org.codehaus.sonar sonar-plugin-api org.codehaus.sonar sonar-colorizer
通过这种改变，Guava jar与所需的其他库一起打包。
