Problems running ktlint

Wrote custom rule(took example from here). Added all into a module, try to run ktlint from main project, get the following error:

FAILURE: Build failed with an exception.

• What went wrong:

Could not determine the dependencies of task ':app:ktlint'. Could not resolve all task dependencies for configuration ':app:ktlint'. Could not resolve project :custom_ktlint_rules.
