1. maven的setting文件配置

<!-- mirrors
   | This is a list of mirrors to be used in downloading artifacts from remote repositories.
   |
   | It works like this: a POM may declare a repository to use in resolving certain artifacts.
   | However, this repository may have problems with heavy traffic at times, so people have mirrored
   | it to several places.
   |
   | That repository definition will have a unique id, so we can create a mirror reference for that
   | repository, to be used as an alternate download site. The mirror site will be the preferred
   | server for that repository.
   |-->
  <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>nexus-osc</id>
		  <mirrorOf>*</mirrorOf>
		  <name>Nexus osc</name>
		  <url>http://maven.oschina.net/content/groups/public/</url>
	  </mirror>-->
	  <mirror>
		  <id>mirrorId</id>
		  <mirrorOf>repositoryId</mirrorOf>
		  <name>Human Readable Name for this Mirror.</name>
		  <url>http://my.repository.com/repo/path</url>
	  </mirror>


	<mirror>
        <id>nexus-aliyun</id>
