Based on the error message, it appears that Jack-enabled builds do not handle all cases where you update Gradle build settings. Jack keeps a cache of pre-compiled stuff (preJackPackagedLibraries), and something that you changed caused Jack to not like that pre-compiled material. Ideally, the build system would detect this case and simply re-compile it, but apparently it does not.

Cleaning the project (Build > Clean Project) hopefully clears up this problem in all cases.
