Error:Execution failed for task

 :app:transformClassesWithInstantRunSlicerForDebug'. java.io.IOException: Failed to delete C:\Users\ashis\AndroidStudioProjects\FirstApp\app\build\intermediates\instant-run-support\debug\restart-changes.txt**

and here is the output:

:app:transformClassesWithInstantRunSlicerForDebug'. java.io.IOException: Failed to delete

-- try to clean project and rebuild project.

From @Kael: A clean is performed via Build -> Clean Project or Build -> Rebuild Project.

(For those who are wondering, that's Build Menu > Clean Project and Build Menu > Rebuild Project)
its not working, when i click clean project it shows the same error"Error:Execution failed for task ':app:mergeDebugResources'. > java.io.IOException: Could not delete path 'xxxxxxxxxx\app\build\intermediates\res\merged\debug\drawable-hdpi-v4'."
@Prasad: Same here.
I know it's not the place for it... but THANKS A LOT.
This happens far too often. Any other way to prevent it from happening?

Kindly follow these steps: Goto 

1>File 2>Settings 3>Build,Execution,Deployment 4>Instant Run 5>Uncheck (Enable Instant Run to hot swap code)

So this helped me.

In my situation Build Menu > Clean Project and Build Menu > Rebuild did NOT work. Instead I had to delete the build folder manually from the filesystem (using Finder on OSX, Explorer on Win).

I had the same problem .. I solved my problem by deleting .gradle file on my project root and rebuilt my project again.

I had Execution failed for task ':app:generateDebugBuildConfig'. error, cleaning and rebuilding project was not working.

  1. I added C:\Users\...\AppData\Local\Android\sdk\tools to my PATH Environment variable.
  2. I closed android studio and vscode that I was using for edit project files. (This is very important)
  3. I run the project and it worked fine.

Change this https://services.gradle.org/distributions/gradle-4.4-all.zip to this https://services.gradle.org/distributions/gradle-4.1-all.zip in grable-wrapper.prperties. And then re import the properties. and sync the project.
