解決辦法：檢視maven倉庫映象是否有問題

出錯的配置：

    <mirror>
        <id>mvnrepository</id>
        <mirrorOf>central</mirrorOf>
        <name>mvnrepository</name>
        <url>http://mvnrepository.com/</url>
    </mirror>
     <!--  配置阿里雲  -->
    <mirror>
        <id>nexus-aliyun</id>
        <mirrorOf>nexus</mirrorOf>
        <name>Nexus aliyun</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>

改為：

將

    <mirror>
        <id>mvnrepository</id>
        <mirrorOf>central</mirrorOf>
        <name>mvnrepository</name>
        <url>http://mvnrepository.com/</url>
    </mirror>
