无法在Eclipse中编译-未处理的事件循环异常

Question

我无法在Eclipse中编译gwt应用程序。但在Eclipse之外的Maven工作。我收到一个与IPixelConverter相关的错误（请参阅下面的完整堆栈跟踪）。Eclipse的版本为3.5.1（SpringSource Tool Suite2.3.0），GWT插件的版本为2.1.0，从3.5更新站点安装。

知道它为什么不起作用吗？

上面我也有同样的问题。

错误发生错误。有关详细信息，请参阅错误日志。com/google/gdt/eclipse/platform/shared/ui/IPixelConverter。

您需要安装/重新安装"Jetty-9捆绑组合存储库"-仅http://download.eclipse.org/jetty/updates/jetty-bundles-9.x清单：Jetty-捆绑包：所有的Jetty捆绑包。
