How can I list which dependencies count against the dex limit for an androidTest apk in AGP 3.0?

问题

I upgraded to AGP 3.0, but then got a com.android.dex.DexIndexOverflowException for the androidTest apk. I didn't have this issue with gradle 2.3.3. How can I get a dependency report for exactly which dependencies are being added only to an androidTestApk (aka dependencies which count against the 65k dex limit)

I tried: ❯ ./gradlew app:dependencies --configuration androidTestApk

androidTestApk - Apk dependencies for 'androidTest' sources (deprecated: use 'androidTestRuntimeOnly' instead). (n)
No dependencies

So I tried: ❯ ./gradlew app:dependencies --configuration androidTestRuntimeOnly

androidTestRuntimeOnly - Runtime only dependencies for 'androidTest' sources. (n)
No dependencies

What should I do?

Note: this issue would be fixed by bumping the minSdk to 21 (but I cannot do that for my main apk)
