should I modify build.gradle

 implementation 'com.facebook.litho:litho-annotations:0.23.0'

instead of

compileOnly 'com.facebook.litho:litho-annotations:0.23.0'

@marco-cova Is that a chance that came from the reflection-based prop comparison?

[marco-cova]

Yes, looks like the Comparable interface is not found in your build for some reason. I would check ProGuard's configuration or anything you use to strip out classes.

[passy]

@marco-cova - @jerboy's comment seems correct in that case. If annotations are now required at runtime, they need to be marked as implementation.

Fixed with ec67371. Thanks for reporting.
