Hi, does anyone facing this warrning??

All the time. It will take some time to fix it

Can you please register an issue with the project in which this reproduces?

Yes, encountered the same issue

Gavriil I can reproduce it with Android Studio Giraffe pretty much with any project, just after a gradle sync. I haven't checked IJ

@Pablichjenkov What are the steps to reproduce, is it stable? I have never seen this "Duplicate roots" warning.
