我正在構建一個android應用程序，並遇到了一些與我的成績構建有關的麻煩。AWS錯誤：Gradle：執行失敗的任務'：應用程序：transformClassesWithJarMergingForDebug'
當我構建「應用程序」作爲一個整體，構建完成（有錯誤），但項目編譯，但這不是我的問題。
我剛寫了一個小的測試程序類，用於我寫的匹配引擎類，並且期待查看控制檯輸出以查看匹配發生的位置。然而，當我嘗試和運行MatchEngineTester類，它不編譯，我得到以下錯誤：
Error:Gradle: Execution failed for task':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/amazonaws/services/cognitoidentityprovider/AmazonCognitoIdentityProviderClient.class
當我運行項目中的任何其他活動或類不會發生此錯誤，只有matchEnginerTester類，它可以發現如下：

任何幫助，將徹底明白，我有一個強大的（ISH）.J ava背景，但是對於android開發來說是合理的新手，尤其是gradle！
我也注意到，他們是堆棧溢出的其他問題非常類似於這個，但已經嘗試瞭解決這些問題（主要是清潔/構建）的解決方案，我仍然處於虧損狀態。
在此先感謝。
