今天在写一个商城项目，SSM框架整合ok了，主要的模块也都搭建好了，但是在最后测试的时候出现了上面这个很有意思的错误，所以写下这篇博客。

在我执行Maven install的时候报了一个No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?，一看见这个报错就知道环境哪里没配置好，最开始以为是JDK的版本问题，我本地装的是JDK1.8，但是项目里都是设置的1.7.百度了一下后找到了下面这个让我很懵的设置。。。


对！就是把一个叫你Install JREs的地方直接换成JDK的路径，换了过后就ok了。
