Android Wear ClassNotFoundException after gradle update

Question

After updating the project gradle wrapper from 2.14.1 to 3.3 and Android gradle plugin from 2.2.3 to 2.3.1 I have a ClassNotFoundException on the wearable application start.

Notes:

If the wearable app pushed directly from the Android Studio to the watch, and not as the part of the mobile release APK, everything works ok.
On the previous gradle version no exceptions.

Exception:

Did you try the solution in this [SO thread](http://stackoverflow.com/questions/36881299/java-lang-classnotfoundexception-after-android-studio-update) where you Clear app cache, Clear app data , Uninstall app then Run/Debug again? — ReyAnthonyRenacia, Apr 13 '17 at 11:08
