Android Studio doesn't compile test classes for Java library modules during Make Project - android-studio

Question

I have a multi-project Gradle build in Android Studio 2.2.3, containing Java library (core and codegen) and Android library (android) modules. Make Project shows executed tasks in Gradle console:
Executing tasks: [:android:generateDebugSources, :android:generateDebugAndroidTestSources, :android:mockableAndroidJar, :android:prepareDebugUnitTestDependencies, :android:compileDebugSources, :android:compileDebugAndroidTestSources, :android:compileDebugUnitTestSources, :codegen:compileJava, :core:compileJava]
But compileJava compiles only the main classpath, not tests, and testClasses tasks for core and codegen are not listed. On the other hand, ./gradlew build does run testClasses.
How can I make Android Studio compile tests for Java library modules as well?

include 'core'
include 'codegen'
include 'android'
Main build.gradle:

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
