Import Gradle's composite build with it's projects issue

Greetings, community...

I've walked through the review of composite build feature support and have done steps, how to configure:

1. Imported two multiproject builds
2. Configured composite between them both

But I have configured settings.gradle script with included builds. And if I try to import composite build, it doesn't imports it's builds. Is there is a way to do it, maybe I'm missing something? Thank you in advance.
