分析：由于公司网络上网需要有代理设置，所以修改了maven安装目录中conf的settings.xml文件中：
<proxies>
<!-- proxy
| Specification for one proxy, to be used in connecting to the network.
|
<proxy>
<id>optional</id>
<active>true</active>active的值为true表示激活该代理
<protocol>http</protocol>protocol表示使用的代理协议，这里是http
<username>proxyuser</username>
<password>proxypass</password>
<host>proxy.host.net</host>
<port>80</port>
<nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>
-->
<!--代理-->
<proxy>
<id>代理标识</id>
<active>true</active>
<protocol>http</protocol>
<username>代理：用户名</username>
<password>代理：密码</password>
<host>代理：服务器地址</host>
<port>代理：端口</port>
<!--nonProxyHosts>local.net|some.host.com</nonProxyHosts-->
</proxy>
</proxies>
在cmd运行：mvn help:system
