在 setting.xml 中加入以下配置：

<!-- 阿里镜像 -->
<mirror>
    <!--This sends everything else to /public -->
    <id>aliyun</id>
    <mirrorOf>central</mirrorOf> 
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>

如果你不想进行全局配置，你也可以在你的项目中单独设置资源库，在 pom.xml 中加入以下配置：

<repositories>
    <repository>
        <id>aliyunmaven</id>
        <url>http://maven.aliyun.com/nexus/content/groups/public/</url>                 
    </repository>
</repositories>

完整 settings.xml 配置
