Trying to play with the new Android data binding (https://developer.android.com/tools/data-binding/guide.html) in a project using kotlin and it fails on the processing of layout resources:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':android-app:dataBindingLayoutsProcessDebugResources'.
