修改 IDEA 默认的Maven配置为阿里源

1. 找到maven下的settings.xml文件

找到mirrors，修改为

<mirror>
    <id>alimaven</id>
    <mirrorOf>central</mirrorOf>
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
</mirror>

2.修改 IDEA设置
File -> Settings -> Build,Execution,Development -> Build Tools -> Maven

修改为刚才修改的settings.xml的路径

3.重启 IDEA
