在Eclipse ADT中生成Gradle時出錯

Question

我有一個使用Eclipse構建的android項目，希望將其遷移到Android Studio。 盡管Android Studio中正常工作的gradle沒有生成文件，我想使用Eclipse ADT的解釋來創建它們在這里 。

但是，當嘗試生成Gradle文件時，只要單擊“完成”，Eclipse就會立即顯示錯誤日志。 我試圖解碼它的意思，但無濟於事。

這是有問題的錯誤：

有人知道這意味着什么嗎？ 代碼可以正常編譯，並且可以在eclipse和Android Studio中運行（沒有gradle），這就是為什么我很傻，為什么我的源代碼肯定沒有任何錯誤導致錯誤

Answer 1

我有同樣的錯誤。 我可以通過在要導出的項目的根目錄中手動創建一個空的“ settings.gradle”文件來解決該問題。 我還必須為其他任何從屬項目（即在導出屏幕的“導出的模塊”區域中顯示的任何模塊）創建它。

希望這可以幫助。
