I believe the problem has nothing to do with your codebase. We started to receive a lot of

error.NonExistentClass

during incremental builds after upgrading to

1.1.4

. Cleaning the project solves the problem, but it makes

kapt

completely unusable. We were forced to downgrade to

1.1.3

.

i had the same problem and 1.1.4-3 seems fixed that
