Java GWT设计师可以'；在项目中找不到GWT模块X

我在GWT应用程序中使用GWT Designer时遇到问题

Can't find GWT module
    GWT Designer can't find GWT module com.google.gwt.query.Query in project. Possible reasons: 

    1. There really are no module with this ID. For example, it was just mistyped or accidentally broken. 
    2. Jar files or project that contains the required module is not included into the classpath of the current GWT project.

它说它在任何地方都找不到这个模块包。我能够通过ANT编译而没有任何问题，我使用IvyDE依赖关系管理进行外部库管理

这是我的项目包结构和错误消息的基本概述。这些库都在那里，只是GWT Designer似乎无法看到它们

有人知道这里发生了什么吗？我试着让它工作，但什么都不起作用。谢谢

无法初始化浏览器

GWT设计器使用web浏览器使用WebKit框架呈现GWT UI。初始化期间，WebKit引擎返回：3:无法解析代理主机名（）

您的问题的解决方案是：

您的项目缺少文件gwt-dev.jar。将其添加到buildpath中并重新启动EclipseIDE
