IntelliJ: Unfortunately you can't have non-Gradle Java modules and Android-Gradle modules in one project

I hit this build problem today after switching between Android development and spring boot microservice development.

Unfortunately you can't have non-Gradle Java modules and Android-Gradle modules in one project

The solution was simple - in IntelliJ:

File -> Invalidate Caches / Restart

Choose Invalidate and Restart

Rebuild after IntelliJ restarts.
