二、setting文件仓库

  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
    <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>
          <mirrorOf>central</mirrorOf>
          <name>aliyun maven</name>
          <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
      </mirror>
      <mirror>
          <id>alimaven</id>
          <name>aliyun maven</name>
          <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
          <mirrorOf>central</mirrorOf>
      </mirror>
      <mirror>
          <id>central</id>
          <name>Maven Repository Switchboard</name>
          <url>http://repo1.maven.org/maven2/</url>
          <mirrorOf>central</mirrorOf>
      </mirror>
      <mirror>
          <id>repo2</id>
          <mirrorOf>central</mirrorOf>
          <name>Human Readable Name for this Mirror.</name>
          <url>http://repo2.maven.org/maven2/</url>
      </mirror>
      <mirror>
          <id>ibiblio</id>
          <mirrorOf>central</mirrorOf>
          <name>Human Readable Name for this Mirror.</name>
          <url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url>
      </mirror>
      <mirror>
          <id>jboss-public-repository-group</id>
          <mirrorOf>central</mirrorOf>
          <name>JBoss Public Repository Group</name>
          <url>http://repository.jboss.org/nexus/content/groups/public</url>
      </mirror>
      <mirror>
          <id>google-maven-central</id>
          <name>Google Maven Central</name>
          <url>https://maven-central.storage.googleapis.com
          </url>
          <mirrorOf>central</mirrorOf>
      </mirror>
      <!-- *仓库在中国的镜像 -->
      <mirror>
          <id>maven.net.cn</id>
          <name>oneof the central mirrors in china</name>
          <url>http://maven.net.cn/content/groups/public/</url>
          <mirrorOf>central</mirrorOf>
      </mirror>
  </mirrors>

配置后打开本地shell，输入mvn help:system ，判断是否可以连接远程仓库

三、遇到的问题

idea中配置pom依赖后无法自动下载到jar包。

查看idea maven配置


在刷新后可以下载到包

如果实在拉取不到包，就重新安装下idea吧
