[问题解决] maven仓库下载缓慢

maven下载jar的时候会去寻国外的地址，因此造成了下载jar很缓慢，影响开发效率，于是就出现maven镜像地址，可以使我们开发人员迅速下载相关的jar。

在maven的config的setting.xml文件中,我们发现:

<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</mirror
4000
Of>
<name>Human Readable Name for this Mirror.</name>
<url>http://my.repository.com/repo/path</url>
</mirror>
-->
<mirror>
<id>CN</id>
<name>OSChina Central</name>
<url>http://maven.oschina.net/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>

mirror的配置就是为了镜像：

国内连接maven官方的仓库更新依赖库，网速一般很慢，收集一些国内快速的maven仓库镜像以备用。

====================国内OSChina提供的镜像，非常不错===================

<mirror>

<id>CN</id>
<name>OSChina Central</name>
<url>http://maven.oschina.net/content/groups/public/</url>
<mirrorOf>central</mirrorOf>

</mirror>

========================================================

OSChina Maven 库使用帮助
