解决：

maven更改镜像路径为阿里镜像。

修改maven根目录下的conf文件夹中的setting.xml文件（或者当前用户目录 的 .m2 目录下的 setting.xml 文件）ps：最好两个文件都改

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