Maven settings 开源中国 镜像并下载本地仓库

如果还没配置好Maven的朋友请先配置好Maven，配置Maven点击：/article/10035302.html

Maven settings文件里面的配置的镜像默认是国外的，由于大天朝的原因呢，下载国外的东西是很慢的，并且很容易出现中断或者下载失败的原因，

基于这个原因呢，2012年，开源中国终于弄了个China镜像，方便国内的Maven使用者：

配置如下：

第一：

<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>
-->
<mirror>
<id>nexus-osc</id>
<mirrorOf>central</mirrorOf>
<name>Nexus osc</name>
<url>http://maven.oschina.net/content/groups/public/</url>
</mirror>
<mirror>
<id>nexus-osc-thirdparty</id>
<mirrorOf>thirdparty</mirrorOf>
<name>Nexus osc thirdparty</name>
<url>http://maven.oschina.net/content/repositories/thirdparty/</url>

</mirror>
</mirrors>

第二：

<profile>
<id>jdk-1.4</id>
<activation>
<jdk>1.4</jdk>
</activation>

<repositories>
<repository>
<id>nexus</id>
<name>local private nexus</name>
<url>http://maven.oschina.net/content/groups/public/</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>nexus</id>
<name>local private nexus</name>
<url>http://maven.oschina.net/content/groups/public/</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
<profile>
<id>osc</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<repositories>
<repository>
<id>osc</id>
<url>http://maven.oschina.net/content/groups/public/</url>
</repository>
<repository>
<id>osc_thirdparty</id>
<url>http://maven.oschina.net/content/repositories/thirdparty/</url>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>osc</id>
<url>http://maven.oschina.net/content/groups/public/</url>
</pluginRepository>
</pluginRepositories>
</profile>

第三：

创建本地仓库目录（目录必须事先建好）

<localRepository>本地仓库路径</localRepository>

然后打开dos命令：
执行：mvn help:system

坐等jar包下到本地仓库吧
