【问题描述】：
我正在尝试设置我的开发环境，但遇到了一个大问题。 我将它设置为运行一个 gwt-gae-maven 应用程序，该应用程序将使用 guice 进行依赖注入，并使用 requestfactory 来持久化数据。 我使用了一个在这里找到的 api https://github.com/etiennep/injected-requestfactory... 看起来很神奇，但对我不起作用。试图在这里做http://www.wanderingcanadian.ca/guiced-up-gwt-requestfactory，但没有任何效果...... 当我尝试将它作为 web 应用程序运行时，我得到了这个异常并且没有任何工作：
1) 自定义提供程序出错，java.lang.RuntimeException：

我也尝试在没有 guice 的情况下运行它，直接在 web.xml 上指定 servlet，但得到了同样的错误（但这次不是在我运行应用程序时，而是在我启动它时）。
尝试了很多东西，但没有任何效果......总是同样的错误。我想这可能只是一个我看不到的细节......我无法继续，直到我修复它......有人知道怎么做吗？
谢谢。

无法解决...我的解决方法是删除项目并重新启动它...现在可以了，不知道出了什么问题。
