GWT Designer无法在项目中找到GWT模块X.

Question

我在GWT应用程序中遇到GWT Designer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.

它说无法在任何地方找到这个模块包。我能够通过ANT编译而没有任何问题，我正在使用IvyDE依赖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。这些库似乎只是GWT Designer无法看到它们。

有没有人对这里发生的事情有任何想法？我试图让这个工作，没有任何工作。谢谢！

无法初始化浏览器

GWT Designer使用Web浏览器使用WebKit框架呈现GWT UI。在初始化期间，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：

您的项目错过了文件gwt-dev.jar。将它添加到buildpath中并重新启动eclipse IDE。
