maven 插件一直下载失败

[kanwode111]

刚接触maven，然后运行了特别简单的代码，一直出现
[INFO] Scanning for projects...

n/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom

插件一直下载不下来，
然后在网上查了，说是中央仓库连不上，然后在setting里面加了镜像，但是还是不行

<mirror> 
           <id>ibiblio.org</id> 
           <name>ibiblio Mirror of http://repo1.maven.org/maven2/</name> 
           <url>http://mirrors.ibiblio.org/pub/mirrors/maven2</url> 
           <mirrorOf>central</mirrorOf> 
           
     </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>    

然后，我手动在网页上试了一下，第一个downloading中的地址http://maven.aliyun.com/nexus/content/groups/public/org/apache/mave
n/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom，可以访问到，然后好多网上说是这两个镜像不能用了，然后又试了特别多别的镜像，仍然不行，还请高手指点一下

试试这样的操作让他从头到尾的刷新一遍
