ClassNotFoundException when using @RxLogObservable annotation of Frodo in Android App



I have some issues after converting one of our Java classes to Kotlin - the first build of the app will work, but further builds seem to miss those converted classes in the compiled project. I pinpointed this to Frodo, which we are using to debug our RxJava functions. I guess this may have something to do with annotation processing in Kotlin, but I don’t see how I can use the kapt examples of the Kotlin blog on the classpath stuff of Frodo…

I made a reproducible test case for this on GitHub:

Any insight on how I can fix this?
