Android上的Scala：無法解析MainActivity;界面540'Lscala/ScalaObject;'

Question

我用這個教程中獲得的Eclipse，斯卡拉和Android運行起來： http://scala-ide.org/docs/tutorials/androiddevelopment/index.html

我也把這個網頁的源代碼示例（刪除MainActivity.java - 創建MainActivity.scala）。

運行應用程序，我得到錯誤信息：

有誰知道什麼是錯在這裏嗎？

我不得不使用斯卡拉-IDE的每晚構建與斯卡拉2.10，那麼它完美的作品。
