maven的web项目打包报错：No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK

打包过程中报错如下：

No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK

 

 

问题原因：

在IDE上运行项目是使用的jre，但是maven打包项目需要使用JDK

 问题解决：

Window --->preferences  --->java   --->Installed JREs ---->Add一个JDK进来
