maven的setting使用

1
  <mirrors>
2          <!--国内阿里云提供的镜像，非常不错-->
3      <mirror>
4          <!--This sends everything else to /public -->
5          <id>aliyun_nexus</id>
6          <!--对所有仓库使用该镜像,除了一个名为maven_nexus_201的仓库除外-->
7          <!--这个名为2441940-release-Kg0bES的仓库可以在javamaven项目中配置一个repository-->
8          <mirrorOf>*,!2441940-release-Kg0bES</mirrorOf>
9          <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
10      </mirror>
11    </mirrors>

<mirrorOf></mirrorOf>的设置很重要，比如上面我设置的mirrorOf为<mirrorOf>central</mirrorOf>，如果<mirrorOf>
</mirrorOf>我随便设置一个参数，如<mirrorOf>abc</mirrorOf>，这时候我们配置的仓库就不起作用了，这是因为
