maven仓库中心mirrors配置多个下载中心(执行最快的镜像

maven的settings.xml配置文件

<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>
      <!-- 唯一标识一个mirror -->
      <id>mirrorId</id>
      <!-- 代表了一个镜像的替代位置，例如central就表示代替官方的中央库 -->
      <mirrorOf>repositoryId</mirrorOf>
      <!-- 貌似没多大用，相当于描述 -->
      <name>Human Readable Name for this Mirror.</name>
      <!-- 是官方的库地址 -->
      <url>http://my.repository.com/repo/path</url>
    </mirror>

     <!--默认的中央仓库-->

      <url>https://repository.jboss.org/nexus/content/repositories/releases/</url>  
    </mirror> 
  </mirrors>

重要说明：

此处指定多个mirrors镜像，镜像只会执行第一个位置mirror。

官网说明如下:http://maven.apache.org/guides/mini/guide-mirror-settings.html

设置多个镜像只会识别第一个镜像下载jar包。配置的多个mirror可以都放着不影响，选取一个镜像下载比较快的放在第一个就行。
