Android: Can't import class from another module

Question

I have an Android app module, an Android library module :foo, and a pure java module :bar. In :foo, I have a Foo class, and in :bar, I have a Bar class.

I would like to reference Foo from my Bar class. When I hover over the Foo variable, Android Studio gives me the following suggestion:

Add dependency on module 'MyApplication.foo.main'

When I do as Android Studio suggests, it adds a dependency in build.gradle for the :bar module. After adding the suggested code, this is what my build.gradle looks like:

build.gradle (:bar)

plugins {
    id 'java-library'
}

java {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

dependencies {
    implementation project(path: ':foo')
}

Except there's one small problem; Foo still can't be resolved! Does anyone know how I can import it?

Here is what my project structure looks like:

So it turns out you cannot add an Android module as a dependency to a pure java module, which I guess makes sense.

Android Studio IDE was just suggesting something that cannot be done, which is misleading.
