IDEA 配置Maven国内源

首先打开设置，在设置中搜索maven，然后跳转到这个页面：

看到有一个User settings files这个项，/Users/xq/.m2/settings.xml这个便是配置文件，修改这个文件即可，如果没有这个文件，可以新建一个settings.xml文件，然后设置为如下内容：（重点是mirrors里的内容，这里用的是阿里源，可以改为其他源）

写入配置文件

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
