I'm testing out Dagger 2 with Kotlin in an Android project. I was inspired by the Android Clean Architecture repo. I have two modules in my gradle build, one is "app" and one is "module". Module contains one class call Model. In my app gradle module I created a dagger module called "DaggerModule" with a Model provider. When I try to build the project, I get compilation errors:
DaggerModule.kt: (3, 57): Unresolved reference: Model
DaggerModule.kt: (9, 34): Unresolved reference: Model
DaggerModule.kt: (9, 42): Unresolved reference: Model
When I try moving the Model class from "module" module to inside of the "app" module everything compiles w/o error. Trying to figure out if I'm doing something stupid, or if I should file a bug somewhere.
For reference here the snippets of the problematic files:

DISCLAIMER: This is my first time test driving Dagger 2 and am a gradle newb. The sample project is the minimum code I could find to display the problem. I'm not expecting it to do much :D.
Your module/build.gradle is set to java instead of kotlin. I have modified it to the following and it compiles ok.
