我正在尝试使用gradle构建一个开源Java项目lilith。但在从cmd行窗口运行gradle时遇到了这个问题：

D:\Opensource\lilith_svn\sulky-master>gradle

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'sulky-master'.

我发现我可以从我的网页浏览器访问目标文件。所以我对有关连接失败的错误信息感到困惑。
或者这是否意味着gradle程序没有访问互联网的权限？如果是，请给予一些解决方法。
谢谢，特里。
