Obscure Dagger 2.0 Error

[Chris Harris]

I'm attempting to migrate from Dagger 1.0 to 2.0 and I am blocked by the following error. Anyone able to tell what is going from the stack trace? Is there a way to get the Dagger compiler to output some extra logging to get some clue what/where the problem is?

Regards,

Chris

Do you maybe use a raw Provider, Lazy or MembersInjector type? (i.e. without type argument)

[Chris Harris]

I do use Providers, but I checked and they do all have type arguments.

I don't use Lazy at all - I always use Providers (even for Singletons)

I don't have any explicit references to MembersInjector in my code, but I do see a lot of warnings like: "Note: Generating a MembersInjector or Factory for XXXXXXX. Prefer to run the dagger processor over that class instead."

I decided to scale back my approach and try injecting only my Application class, but then the compiler is going to max CPU and eventually runs out of memory (OutOfMemoryError). Has anyone ever seen this?

Thanks,

Chris
