org.apache.maven.surefire 无法引用或无法下载问题

问题报错：

Failure to transfer org.apache.maven.surefire:surefire:pom:2.10 from http://repo.maven.apache.org/maven2 was cached in the local repository,

resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer
artifact org.apache.maven.surefire:surefire:pom:2.10 from/to central ( http://repo.maven.apache.org/maven2): java.net.ConnectException:

connection timed out to http://repo.maven.apache.org/maven2/org/apache/maven/surefire/surefire/2.10/surefire-2.10.pom

错误原因：

org.apache.maven.surefire    没有配置    和 http://repo.maven.apache.org/maven2  连接不上的问题


解决方式：

   在pom.xml文件中 注意配置如下内容：

      
           
                org.apache.maven.plugins
                maven-surefire-plugin
                2.7
           
    


   其次 如果还报 connection timed out ，请再setting.xml添加仓储镜像解决，比如使用阿里云的仓储镜像速度非常快，配置如下：

   
      alimaven
      aliyun maven
      http://maven.aliyun.com/nexus/content/groups/public/
      central
