java - while - unity transformdexarchivewithexternallibsdexmergerfordebug




Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.> (2)

A workaround: I Solved a similar issue through the following steps: Menu -> Build -> Clean project. Then try to build your project again. Hope it helps.

My project was running well but suddenly it starts raising an ERROR:

Gradle build finished with 1 error(s)

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 1 path $

It raises on both Android Emulator and Real Device.

I tried to

  • delete .gradle folder on root of the project
  • re-make and re-sync project
  • close and open Android Studio
  • Restart Windows
  • Change API (26, 27)

BUT no success.

Android Studio 3.0.1

EDIT 1: It seems that it's caused by com.google.code.gson:gson:2.8.2

Here's the gradle console output with stack trace:
