A modern programming language that makes developers happier.

kotlinlang

I'm having a hard time updating to Android Studio 3.0 beta2. I'm using Kotlin `1.2-M2` and build tools `26.0.1` everything is working except extension functions across modules. I have one module `sdk`, then modules `wear` and `app`. In `sdk` I have a simple extension function:
```
fun Context.hasPermission(permission: String): Boolean =
        ContextCompat.checkSelfPermission(this, permission) == PackageManager.PERMISSION_GRANTED
```

But when I use it outside of the `sdk` module I'm getting `Unresolved reference: hasPermission` (this wasn't the case before updating to build tools 26 / Android Studio 3.0. Does anyone know if I need to do anything special to export extension functions to other modules?
