Above site introduced clean architecture.

And I know the position of repository interface is domain.

Google Android team introduced repository pattern. And this positioned "repository interface" at data layer.

Also Google Android team sad the domain layer is optional.

It makes me confusing a little.

("Now In Android" project also positions the repository interface at data layer.)

If I want use "domain layer" for some feature and modularaization it, it can't be test without dependency with data layer. And If the data layer changed so repository interface changed, useCase also must be changed.
