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

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

You can simply downgrade your gradle dependency to fit your current android studio version.

dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'
        ....
}

Worked for me.
