Answer 1

1. Install the latest Gradle version (1.10.2 at the moment of writing).

2. Install the latest version of Kotlin plugin: go to Settings Ctrl+Alt+S > Languages & Frameworks > Kotlin Updates > select Update channel > click [Check again]
   My current Kotlin plugin version is 1.3.0-rc-57.

3. Execute Build > Clean Project to remove temporary gradle files.

4. File > Invalidate Caches / Restart...

5. After restarting Sync Project with Gradle files and Make Project (Ctrl+F9).
