maven 运行报错 rather than a JDK?

maven编译项目时出错，提示信息如下：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:testCompile (default-testCompile) on project hqnymngr: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
[ERROR] -> [Help 1]

看到是JDK 的问题，首先要检查一下build path 中的jdk是否正确，之后再打开prefrences 中的java下面的Installed JREs中的jdk是否正确，操作完之后一定要刷新项目，刷新项目，刷新项目，再去执行maven install
