GWT Note 1

今天遇到一個很怪的情況，怎麼加xxx.gwt.xml在已含有*.gwt.xml的project內就是會跑不起來，訊息如下:
[ERROR] [gwtevents1] - Unable to find 'gwtevents1.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?
...
[ERROR] [gwtevents4] - Unable to find 'gwtevents4.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

這四個新加入的都出現一樣的錯誤，後來才找到問題:就是不要跑原先存留在eclipse內的執行設定，也就是刪除舊的執行設定 Run => Run Configurations => delete old configuration 或對project按右鍵=>Run As => Web Application

這種問題的解決挺難找的= = ，如果習慣用ant或maven來build，不要仰賴eclipse就不會遇到這種鳥事。
