Maven 构建 CAS 服务器失败

Question

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

有人说这是代理问题，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>

还是没有运行，谁能指出错误？

为什么不从 Maven 中心下载 jasig-parent 呢？
