Grails 权限被拒绝错误

Question

我正在尝试运行 Grails 应用程序，我从 SVN 存储库中检查了它，但出现以下错误！

当我尝试导航到该链接时，它给了我一个 404 错误。我该如何解决这个问题？

Answer 1

Grails 正在尝试通过自动下载它们来解决应用程序的依赖关系，但由于某种原因无法访问这些站点。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）。请参阅this answer 了解如何处理它。该答案仅处理 Spring Security Core 依赖项，但该解决方案将适用于您的所有依赖项。

Answer 2

出现错误时我已连接到 VPN，我已断开与 VPN 的连接，一切正常！

Answer 3

听起来您在连接到存储库时遇到了问题。这可能是由于试图从防火墙后面访问它们。配置代理将有助于解决其中的许多问题。

Example:
grails add-proxy client --host=proxy-server --port=4300 --username=guest --password=guest
grails set-proxy client
