Dagger not finding an Autofactory generated class after updating to 2.18

I’m running into a strange thing trying to update from Dagger 2.16 to 2.17/18 Dagger fails, complaining an AutoFactory generated class isn’t present.

If I copy the AutoFactory generated implementation into my code and remove the @AutoFactory annotation, then everything compiles fine. I haven’t found anything that’s obviously different about this class, and I haven’t been able to reproduce it yet. There are three other AutoFactory classes in the same package which work fine once this one is removed. The Factory class does seem to be generated too, just Dagger doesn’t see it.

The relevant bit of the stack trace when building with 2.18 is

Try this in build.gradle:

kapt {
    correctErrorTypes = true // https://github.com/google/dagger/issues/435#issuecomment-441723285
}

I believe I have the same issue but not 100% sure - is there an easy way to try out future releases? Any beta releases out there?
