Grails权限被拒绝错误

我试图运行一个Grails应用程序，我从SVN repo中检查了它，我得到了以下错误

Server access Error: Permission denied: connect url=http://grails.org/plugins/grails-mysql-connector-java/tags/RELEASE_5_1_20/mysql-connector-java-5.1.20.pom

当我尝试导航到链接时，它会给我一个404错误。如何解决这个问题？

Grails正试图通过自动下载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。看看如何处理它。这个答案只处理Spring Security核心依赖项，但解决方案将适用于您的所有依赖项。

当我收到错误时，我连接了VPN，我断开了与VPN的连接，一切正常

听起来您在连接存储库时遇到了问题。这可能是因为试图从防火墙后面访问它们。配置代理将有助于解决其中许多问题

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

Grails正在尝试解决依赖关系。你能从那台计算机上访问这些URL吗？你在buildConfig的什么地方定义你的mysql连接器？
