我正在尝试运行Grails应用程序，我从SVN repo中检出了它，我收到以下错误！

Grails试图通过自动下载来解决应用程序的依赖关系，但无论出于何种原因都无法访问这些网站。您需要使这些依赖项可访问（最简单的方法是手动安装它们）。有关如何处理，请参阅this answer。答案仅涉及Spring Security Core依赖项，但该解决方案适用于所有依赖项。

当我收到错误时，我与VPN连接，我从VPN断开连接，一切正常！

听起来您无法连接到存储库。这可能是因为尝试从防火墙后面访问它们。配置代理将有助于解决许多这些问题。
Example:
grails add-proxy client --host=proxy-server --port=4300 --username=guest --password=guest
grails set-proxy client
