我正在努力设定我的发展环境而且我遇到了一个大问题。 我将它设置为运行gwt-gae-maven应用程序，该应用程序将使用guice进行依赖项注入和requestfactory来保存数据。 我使用了一个我在这里找到的api https://github.com/etiennep/injected-requestfactory ...它看起来很神奇，但对我来说不适用。试着像http://www.wanderingcanadian.ca/guiced-up-gwt-requestfactory那样做，没有任何作用...... 当我尝试将其作为webapplication运行时，我得到了这个异常并且没有任何作用：

此外，我尝试在没有guice的情况下运行它，直接在web.xml上指定servlet，但是得到了相同的错误（但这次不是在我运行应用程序时，而是在我启动时）。
尝试了很多东西而没有任何效果......总是出现同样的错误。我认为这可能只是一个我看不到的细节......我不能继续，直到我解决它......有人知道如何做？
感谢。
答案 0 :(得分：0)
无法解决它...我修复它的方法是删除项目并重新启动它...现在它可以工作，不知道出了什么问题。
