Question

我正在處理一個問題，我知道問題在哪里，但我不知道如何解決。 當我嘗試使用運行方式-> Web應用程序運行開發服務器時，在控制台上出現以下錯誤：

我知道路徑“ C：\\ Users \\ JOSR \\ Last Hope \\ WEB-INF / appengine-web.xml”錯誤，應為“ C：\\ Users \\ JOSR \\ Last Hope \\ war / WEB-INF / appengine- web.xml”，但我不知道在哪里更改它或如何強制GWT使用正確的戰爭路徑。 有任何想法嗎？

謝謝閱讀！

Answer 1

從上下文菜單

運行方式/運行配置，然后選擇html，選擇Arguments標簽

-war選項就是那個。

Answer 2

在GWT-GAE項目中開始使用Maven時，我遇到了同樣的問題。

在我的情況下，發生此問題是因為Eclipse啟動文件試圖從target/myproject/WEB-INF/appengine-web.xml加載appengine-web.xml，但是文件位於src/main/webapp/WEB-INF 。

解決方案是從Eclipse中的項目屬性中取消選中“從此目錄啟動並部署（由於這是Maven項目而被禁用）”選項，即使它確實是一個Maven項目，如圖中的“ WAR目錄： ”應指向src/main/webapp

重要 ！ 請記住，您必須在運行啟動文件之前使用maven構建項目，否則文件夾target/myproject/WEB-INF/將為空。
