Today I tried to build an Android Studio that was written by someone else three years ago. After some initial progress I got stuck with Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception. After hours of struggle and fruitless trials, I finally looked at the details of the Gradle stack trace and saw that the top message was Execution failed for task :app:mergeDebugResources and the bottom message was com.android.builder.png.AaptProcess$NotifierProcessOutput.out.
My problem was due to an image file name ending with .9.png. I changed the ending to .png and the problem disappeared. Thanks Gradle for the cryptic concurrent.ExecutionException (!) This sort of unhelpful error messages is a typical theme when developing Android apps, especially when dealing with legacy code. You can get stuck for days on problems that you could not have foreseen.

With Andy Studio, you spend twice as much time debugging gradle as you spend writing code. What a waste of one's life
