    <mirrorOf>*</mirrorOf>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>
<mirror>
      <!--This is used to direct the public snapshots repo in the
          profile below over to a different nexus group -->
      <id>nexus-public-snapshots</id>
      <mirrorOf>public-snapshots</mirrorOf>
      <url>http://maven.aliyun.com/nexus/content/repositories/snapshots/</url>
</mirror>
