解决Perhaps you are running on a JRE rather than a JDK?问题

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

问题描述：No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

翻译过来就是，大哥，环境里没给编译器呀，可能你是用jre在玩耍，我要jdk~~

 

问题原因：eclipse官网看了看，发现eclipse默认是运行在jre上的，
但是maven插件需要使用jdk，因此需要在eclipse修改Installed JRES
位置在-->【Window】-->【Prefrences】-->【Java】-->【Installed JREs】
详见下图。

重新运行一下，问题完美解决。。。。。。。。。。。。。。。
