eclipse整合maven下载jar包速度慢问题解决

引用：http://blog.csdn.net/u010154380/article/details/70339538

开发过程中在pom.xml中添加pom的时候，默认是需要从中央仓库中下载，但是下载的速度是非常慢的，超过一定的时间可能就觉得是eclipse卡死了。 
解决办法是在maven中添加阿里的镜像。 
具体的操作步骤是： 
1.找到maven安装目录下conf文件夹下的settings.xml文件 
2.在mirrors中添加阿里的镜像

<mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
