GWT Designer m_selectedModule文件錯誤

Question

這是我第一次與GWT合作。我正在學習以下教程：http://code.google.com/webtoolkit/tools/gwtdesigner/tutorials/stockwatcher.html

我無法超越創建GWT Java項目。當我點擊完成時，我得到：發生錯誤。查看錯誤日誌以獲取更多詳細信 m_selectedModuleFile

，當我看看錯誤日誌我得到：

    and so on... 

此外，當你用WinBuilder，當你應該使用GWT Designer或Web應用程序項目？我不確定他們之間的差異。我正在尋找的東西不是可以與App Engine一起使用的一些表單條目。

Answer 1

事實證明，我有一箇舊版本的WindowBuilder，這是造成這個問題的原因。但不知道這是否是整個問題。迄今爲止工作。

Answer 2

這似乎是在安裝中可能會關閉的東西。我通常會安裝Eclipse Java EE版本（不同於Java），然後是GPE減去Android部件（除非我需要爲此設置安裝SDK，然後在GPE之前安裝Android SDK），然後安裝WindowsBuilder - 用於額外的嚮導。之後，一切正常。我創建了一個新的GWT項目（使用示例代碼 - 更容易開始），然後可以使用任何嚮導。
