Error: Execution failed for task ':app:clean'. Unable to delete file

Question

I\'m trying to rebuild my Android Studio Gradle project (containing mostly Kotlin code), but it started to throw an UnableToDeleteFileException during the clean

Answer 1

I had the same problem and this worked for me:

1. close Android Studio.
2. delete intermediates directory (as long as Android Studio is opened, this directory can't be deleted)
3. open Android Studio again
