Android studio build apk失败了

Question

我在生成apk时遇到以下错误或当我尝试将应用程序部署到设备时，我在删除.gradle和build文件夹后重新启动了工作室但是它没有帮助我尝试了无效缓存并重新启动选项我仍然得到这个错误。

Error:Execution failed for task 
':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> java.lang.RuntimeException: 
com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex


:app:transformDexArchiveWithExternalLibsDexMergerForDebug FAILED

* What went wrong:
