I am using @Deprecated(...) in my Kotlin library but from a plain Java project, the deprecation is not shown. Is that a known issue or is there anything wrong with my setup? 🤔

[Lukas K-G]

I have searched the internet and found this which indicates it should work and also some comments that suggest it should not. 🤷 My suspicion is this should work, but I am unsure why it does not.

I can see @kotlin.Deprecated in the decompiled class files, but no @Deprecated .

Is your library available in Maven? Can you share code to reproduce?

[Lukas K-G]

Hi @Alexey Belkov [JB], thanks for answering. Unfortunately I am talking about a closed - source project, so I can’t share easily. (I can try to create a minimal sample though if required).

I found a workaround for this, which is forcing the latest stable R8 version:
classpath 'com.android.tools:r8:2.2.60'
I suspect this issue to be the problem.

[Alexey Belkov [JB]]

Oh, I see, so it's an R8 bug.

[Lukas K-G]

Yes, it seems like. Sorry for not updating here, I thought this conversation was log lost. 😅
