That seems quite bad :/ weird.
We have fairly large test projects which do not take anywhere close to it, maybe your code is triggering some bad code path.

Can you provide a sample or share  your project with us? It is impossible to do something here unless we have a reproduction case. Might also possibly be related to your machine configuration.

Let me see what I can do on the reproduction as I am anyways blocked on this. I will try to extract out the DB module in a new project and see if it reproduces the issue.

Attaching the sample project. When I run the project through the android studio or even command line, I see the described issue.
Try uncommenting room-compiler dependency from app's build.gradle, it does not have the issue because room compiler is not at work.
