We are running in Gradle CI issues that seem to be caused by this change (although the CI for this PR looked green).
I'm opening a PR to revert this change until we figure out why these changes are not enough.

Sorry about that. Actually, I was surprised that the CI completed successfully in 10 minutes.

I think I found the issue with this PR. getProviders().exec() is a lazy method and it won't be triggered unless we call getProviders().exec().get(). Anyway, I opened another PR with alternative implementation.
