app:mergeReleaseResources exception when making release build

Question

I am able to create debug build but release build fails with app:mergeReleaseResources and Error: java.util.concurrent.ExecutionException: exception. I have tried setting progaurd off, remove any corrupted png file but still same issue is coming. Any idea what is going wrong here or how to find the reason?

Answer 1

Solved this by using this command gradlew --scan assembleRelease in terminal and it it gave me following error : D:\Freelance Work\InstaConnect\app\src\main\res\drawable-nodpi\blacktoblue_gradient.png: error: failed to read PNG signature: file does not start wi th PNG signature.

Once i corrected that file , it worked.
