Incompatibility:org.codehaus.plexus. .exception.ComponentLoo

Question

当我试图在我的项目上运行 mvn sonar:sonar 命令时，我经常得到以下错误:

我已经浏览了很多资源或链接，并且知道只有当我们使用不同版本的java编译器时才会出现兼容性问题。虽然我在java 8上运行我的java代码，但我仍然可以看到上面的错误。

版本细节:
Java: 1.8
Maven: 3.0.5
SonarQube: 5.4

有人能帮我解决这个问题吗

Maven本身必须使用Java 8来执行声纳Maven插件。使用mvn --version检查是否使用Java 8。如果没有，调整JAVA_HOME环境变量以指向Java 8安装。
