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

Question

I have an IntelliJ 14.1.2 Project consisting of two modules - one is an Android Gradle based module and the other is a Spring Java-based module with Maven.

Answer 1

In my case settings.gradle contained invalid configuration.

I changed:

include ':app'
rootProject.name=''

To:

include ':app'

Error is gone. So maybe check your settings.gradle for potential errors. If this won't work try to remove cache and other tips.
