本文介绍了一个关于SonarQube Maven Plugin在执行项目扫描时遇到的问题及解决办法。主要错误为组件加载失败，导致项目构建无法完成。通过检查任务管理并移除重复任务解决了project冲突问题。

sonar 访问地址：类似的函数还有printf()，调用的是wirte()系统调用来输出字符串
http://10.37.124.178:9000/batch/project.protobuf?key=com.mpms%3Ampms-pom%3A2017.12.18

返回的是 project.protobuf 文件

在setting-> 项目->Managerment后台查看 com.suning.mpms 任务信息，发现有两个重复的任务！重复导致 project 冲突，进行删除，再次构建。
