一、使用sts (spring tools suite )开发maven项目，再执行run as -> maven install执行错误.错误主要提示：

注意
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

这是因为sts安装默认是选择jre来运行程序的，而maven的的一些功能要求使用JDK。解决方法是配置sts的jre,修改成jdk。

修改后看起来是这样:

最后选中你当前项目  右键该项目 -> Maven -> Update Project
