IDEA mvn package:No compiler is provided in this environment. Perhaps you are running on a JRE

mvn打包的时候报错:No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

百度了一下，有几种原因，最终发现，我的报错有两个原因：

1.language level要与jdk版本不一致

2.maven配置有错

应该选择正确的jdk的路径

 

修改D:\Maven\apache-maven-3.6.1\bin\mvn.cmd，这个文件

在第一行添加：set JAVA_HOME=D:\JDK1.8\installation
