maven配置指南

打开maven的配置文件(windows机器一般在maven安装目录的conf/settings.xml)，在<mirrors></mirrors>标签中添加mirror子节点:

<mirror>
    <id>aliyunmaven</id>
    <mirrorOf>*</mirrorOf>
    <name>阿里云公共仓库</name>
    <url>https://maven.aliyun.com/repository/public</url>
</mirror>

如果想使用其它代理仓库,可在<repositories></repositories>节点中加入对应的仓库使用地址。以使用spring代理仓为例：

<repository>
    <id>spring</id>
    <url>https://maven.aliyun.com/repository/spring</url>
    <releases>
        <enabled>true</enabled>
    </releases>
    <snapshots>
        <enabled>true</enabled>
    </snapshots>
</repository>
