"Unable to resolve dependency" error when runtime is not build

[vtrifonov]

When you open the test-app from the project in android studio and you haven't built the runtime project and run gradle sync you'll get:

ERROR: Unable to resolve dependency for ':app@debug/compileClasspath': Failed to transform file 'runtime-regular-release.aar' to match attributes {artifactType=processed-aar} using transform IdentityTransform

Affected Modules: app

After building the runtime project the errors disappear.
