依赖导不进去？看解决步骤：
1、mirrors标签下把镜像改为：
tips：项目右键Maven -》open ‘settings.xml’

   <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>alimaven</id>
          <name>aliyun maven</name>
          <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
          <mirrorOf>central</mirrorOf>
      </mirror>-->

2、mvn clean
3、项目右键Maven -》Reload project
