我正在尝试实现 SSO 功能并从http://www.jasig.org/cas/download下载所有项目和 pom.xml 。
所以，我得到了我的 maven 项目，然后在 eclipse 中我只是导入为现有的 maven 项目。
然后我将项目作为 MVN CLEAN 运行，但它没有运行并出现错误

有人告诉这是代理问题，所以我更改了 settings.xml 文件以将代理放置为
<proxy>
<id>123</id>
<active>true</active>
<protocol>http</protocol>
<username>abc.def@xyz.com</username>
<password>xyz1233</password>
<host>proxy.com</host>
<port>80</port>
<nonProxyHosts>google.com</nonProxyHosts>
</proxy>
它仍然没有运行，有人可以指出错误吗？
