[meta-task] Kotlin outstanding issues

See original GitHub issue

This issue is to keep track of remaining issues and where applicable work-arounds when using Litho with Kotlin.

Issues

Cannot use Kotlin objects for specs.
Annotated methods inside specs require @JvmStatic.
@PropDefault doesn’t work.
@PropDefault requires @JvmField annotation.

Other Gotchas

kapt is a pig. There seem to be a bunch of invalidation bugs that force you to clean your cache and rebuild.
NonExistentClass shows up in random places. Again, this appears to be a kapt bug and the best workaround for now appears to be ./gradlew clean.

Future work

We should consider generating Kotlin code to fully leverage the new language features like data classes, allow for Anko-like DSLs and get rid of builders.

I’ll update the comment. As long as we don’t use it in production internally, I think it’s best to keep the note there to set the right expectations.

@passy I think it can be closed and also remove the IMPORTANT notice from this doc: https://github.com/facebook/litho/blob/master/docs/_docs/getting-started/gradle-kt.md
