请问如何使用sonar进行代码覆盖率检测？

Question

@hi-alonesword 你好，想跟你请教个问题：

本人想使用sonar进行代码检测，根据网上教程已经成功启动了sonar服务器为http://localhost:9000,并使用用maven新建了一个helloworld程序，使用maven install 编译成功，但是使用 maven sonar:sonar 命令后，得到报错：
望大侠指点迷津!感激不尽！

@hi-alonesword  pom.xml 内容如下，改绝对路径了情况一样，求指导怎么修改。。。

Answer 2

确保运行  mvn install 的目录与  mvn sonar:sonar 目录一致？

或在 pom.xml 中先将路径写成绝对目录，看看运行是否正确？

Answer 3

pom.xml里build标签下我也加入了标签 <sourceDirectory>src</sourceDirectory> <outputDirectory>target/classes</outputDirectory> 还是一样的报错。。怎么弄才对呢？

Answer 4

而且为什么用mvn install 命令就能得到编译成功的提示呢？使用mvn sonar:sonar 就会报出这样的错误呢？

Answer 5

根据日志来看，检查一下 Pom.xml 文件定义的源码路径是否正确。

主要错误： java.lang.NoClassDefFoundError: org/sonar/api/utils/SonarException
