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

Maven构建项目报错：

 

 

解决办法：
　　1、eclipse菜单 -  Window - Preferences- Java - Installed JREs 将配置的JRE定位到JDK，例如JRE home：D:\Program Files (x86)\Java\jdk1.6.0_45
　　2、ALT+F5 进行  update project 。
　　3、Debug or Run again.
