我正在尝试为我的一个项目获取声纳报告。
我已经mvn clean install
Running blah.blah.BlahTest1
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.016 sec
Running blah.blah.BlahTest2
Tests run: 3, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.078 sec
当我运行mvn sonar:sonar时，我收到了波纹管错误。

我不知道从哪里开始寻找。我尝试在谷歌搜索找不到类似于我的问题。
请帮助我理解哪些可能是寻找的原因。
感谢。
添加pom文件：删除了一些细节以缩短文件

我不是Maven专家，但是，我有实现，其中，在maven生命周期中，我执行一些JUnit来找到Code Coverage和Sonar，当然。我附上了我的pom。也许这有帮助。
