Error:Execution failed for task ':app:mergeDeb

Question

currently I am using Android Studio 2.1 when I run my App it shows me some error in Message Gradle Build saying the following

 Information:Gradle tasks [:app:clean, :app:generateDebugSources, :app:prepareDebugUnitTestDependencies, :app:mockableAndroidJar, :app:generateDebugAndroidTestSources, :app:assembleDebug]

I tried cleaning and rebuilding it but it didn't work. The answer for this question didn't work also. Any help would be appreciated, thanks.

Updated: Here is the log output

* Exception is:

Answer 2

compress the project file and delete prjct. and extract it and open

Answer 3

For me, I was getting this error because the full path to the folder was longer than allowed by Windows. I moved my build to a shallower path and this error went away.

Answer 4

Try running gradle from command line:

gradle clean build --debug

And post your log afterwards.

Answer 5

For me, it was a corrupted PNG file. Go to your res folder and try to open every images.

Answer 6

Actually, image file something wrong. Go to (drawable) and remove image or replace with new image.This will solve problem.

In addition, you can put method in (build.gradle), but This will not solve the problem but good way to catch up what was wrong.

In build.gradle, section android {}, insert (cruncherEnagle = false)apptOptions.
