修改Maven源为阿里巴巴的镜像

在C:UsersAdministrator.m2创建setting.xml文件，内容如下

<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
                          https://maven.apache.org/xsd/settings-1.0.0.xsd">
 
      <mirrors>
        <mirror> 
            <id>alimaven</id> 
            <name>aliyun maven</name> 
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url> 
            <mirrorOf>central</mirrorOf>         
        </mirror> 
      </mirrors>
</settings>
