Kotlin LayoutSpec files not found by the Processor about litho

[ubuntudroid]

Okay, got it working as well. I created a minimalistic project on Github pointing out Kotlin specific adaptions: https://github.com/ubuntudroid/litho-kotlin.

Legacy kapt used to convert kotlin code into stub class files, which in turn were run through the javac annotation processing tool. One of the (many) limitations of this idea is that class files don't have any information about method parameter names, which this library depends on. Lots of information in this article: https://medium.com/@workingkills/pushing-the-limits-of-kotlin-annotation-processing-8611027b6711

Are you using kapt3 or legacy kapt? I'm not certain, but I don't think legacy kapt will work with litho.

[agrosner]

looks like legacy KAPT. Is there a reason why legacy won't work? Its strange that java files work in kapt but not Kotlin files.

[agrosner]

ok. now that would make a lot more sense. would it be possible to add this in the getting started docs or somewhere else so it's clear? Thank you!

I have yet to try using Litho with Kotlin. If you want to start some docs on how to do it, we'd certainly love to include it.

@grandstaish According to #119 it seems you got Litho to work with Kotlin. For some reason I'm running into the same problem like @agrosner meaning nothing gets generated. Would you mind setting up an example project so that we can compare our configurations?

Irrelevant! Project already contains a Kotlin sample now :)! Can be closed!
