Grails權限被拒絕錯誤

Question

我想運行一個Grails應用程序，我檢查了它從SVN回購，我得到以下錯誤！

當我嘗試導航到鏈接時，它給了我一個404錯誤。我該如何解決這個問題？

Answer 1

Grails正試圖通過自動下載它們來解決應用程序的依賴關係，但無論出於何種原因無法訪問這些網站。您需要使這些依賴關係可訪問（最簡單的方法是手動安裝它們）。請參閱this answer瞭解如何處理它。這個答案只涉及Spring Security Core依賴，但該解決方案將適用於所有的依賴關係。

Answer 2

當我得到錯誤時，我與VPN連接，從VPN斷開連接，一切正常！

Answer 3

這聽起來像您連接到存儲庫時遇到問題。這可能是因爲試圖從防火牆後訪問它們。配置代理將有助於解決許多這些問題。

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