找了一上午的问题，后来才发现maven也是需要配置代理的，很难受了。

操作步骤：

1、打开{M2_HOME}/conf/settings.xml文件，注意：{M2_HOME}为maven所在目录。

2、找到proxies节点

把上面的注释去掉，然后修改成代理的地址即可。

 
   ...
   
      
         my-proxy
         true
         http
         192.168.10.117
         8080
         
      
    
   ...

这段配置十分简单，proxies下可以有多个proxy元素，如果你声明了多个proxy元素，则默认情况下第一个被激活的proxy会生效。这里声明 了一个id为my-proxy的代理，active的值为true表示激活该代理，protocol表示使用的代理协议，这里是http。当然，最重要的 是指定正确的主机名（host元素）和端口（port元素）。上述XML配置中我注释掉了username、password、nonProxyHost 几个元素，当你的代理服务需要认证时，就需要配置username和password。nonProxyHost元素用来指定哪些主机名不需要代理，可以 使用 | 符号来分隔多个主机名。此外，该配置也支持通配符，如*.google.com表示所有以google.com结尾的域名访问都不要通过代理。
