用Maven新建项目的时候控制台出现如下提示：
[FATAL_ERROR] Cannot start Maven: No valid Maven installation found. Either set the home directory in the <a href="#">configuration dialog</a> or set the M2_HOME environment variable on your system.
极大可能是Maven的setting.xml文件路径或者是repotistory路径无效
点击File,在Setting中找到Maven相关配置，设置为有效路径即可：
