Error:Execution failed for task ':app:buildInfo Debug Loader'

Question

I updated few days ago to Android Studio 2.0 and everything worked fine, but today when I tried to compile the project, I received the following error in the Logcat:

Error:Execution failed for task ':app:buildInfoDebugLoader'.

Exception while doing past iteration backup : Source \app\build\intermediates\builds\debug\184802777347678\classes.dex and destination \app\build\intermediates\builds\debug\184802777347678\classes.dex must be different

The error tells me that the same .dexmust be different, so I'm quite confused. How could I solve it?

anybody looking for more info on what .dex file is go here http://stackoverflow.com/questions/7750448/dex-file-in-android — Raja, Apr 21 '16 at 23:34

Clean Your project.
And try to rebuild it.

If you did it then enable mutidex in app base build.gradle file.

multiDexEnabled true

Just add below line in your app Gradle dependencies

compile 'com.android.support:multidex:1.0.0'

and then below line in defaultConfig

multiDexEnabled true

The way I solved the problem was by just deleting the file!

I am using Android Studio 2.2.1 and had the same error. I resolved this by deleting the folder containing the classes.dex file. In my case it was in the 32129143802723 folder from C:\Users\ME\AndroidStudioProjects\myApp\app\build\intermediates\builds\debug\32129143802723\classes.dex.

From the menu bar I went to File the selected Invalidate Caches/Restart... Then Invalidate and Restart option.

That fixed the issue. The error was gone and I was able to launch the app. Hopes this helps.

So I just cleared the data on the app installed on the phone, and then uninstalled the app. Next time I ran it, it worked without any problems.

I solved it renaming folder "build" inside my project folder. When you build again, android studio creates a new build folder.
