IntelliJ IDEA添加MAVEN插件
https://www.cnblogs.com/LaoJiangLJ/p/8973225.html

打开 File → Other Settings → Default Settings 

修改MAVEN默认的地址，重新选择配置文件

☆特别注意，在配置的时候一定要选择 Default Settings要不然每次新建其他工程都会默认使用IDEA自带的MAVEN

修改MAVEN安装路径下conf文件中的settion.xml文件
1.设置默认仓库地址（我这里设置的是本地D:\JAVATools\MvnRepo） 

2.设置MAVEN的远程仓库路径，默认的地址由于国内特殊原因比较慢，我一般只用了第一个阿里的远程仓库
