C:\Users\nikey\.m2\settings.xml

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <!-- localRepository
     | The path to the local repository maven will use to store artifacts.
     |
     | Default: ${user.home}/.m2/repository
    -->

    <mirrors>
        <!-- 阿里云镜像 -->
        <mirror>
            <id>nexus-aliyun</id>
            <name>Nexus aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
            <mirrorOf>central</mirrorOf>
        </mirror>

        <!-- 给定仓库的下载镜像。 -->
        <mirror>
            <!-- 该镜像的唯一标识符。id用来区分不同的mirror元素。 -->
            <id>alimaven</id>
            <!-- 镜像名称 -->
            <name>aliyun maven</name>
            <!-- 该镜像的URL。构建系统会优先考虑使用该URL，而非使用默认的服务器URL。 -->
            <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
            <!-- 被镜像的服务器的id。例如，如果我们要设置了一个Maven中央仓库
           （http://repo.maven.apache.org/maven2/）的镜像，就需要将该元素设置成central。这必须和中
            央仓库的id central完全一致。 -->
            <mirrorOf>central</mirrorOf>
        </mirror>


    </mirrors>
</settings>
