IllegalStateException after obfuscation

See original GitHub issue

Receiving ISE on creation of RealmConfiguration on release build which got obfuscated with Dexguard. Error message:

Caused by: java.lang.IllegalStateException: Couldn't find companion object of class 'ProductEntity'.
2022-04-06 10:55:01.901 32219-32219/? E/AndroidRuntime: A common cause for this is when the `io.realm.kotlin` is not applied to the Gradle module that contains the 'ProductEntity' class.

Added these rules for RealmObject classes which didn’t help:

-keep,includedescriptorclasses class com.projectname.data.vo.**$$serializer { *; }
-keepclassmembers class com.projectname.data.vo.** { *** Companion; }
-keepclasseswithmembers class com.projectname.data.vo.** {
    kotlinx.serialization.KSerializer serializer(...);
}

Is there any additional configuration needed for it? Or is it rather general misconfiguration of Dexguard on my side? Any kind of these issues are not happening on pre-KMM version of project.

In the end issue was not with Proguard/Dexguard. It got fixed after updating gradle plugin from 7.0.4 to 7.1.2. Cannot understand why it didn’t affect the debug build though.

@tarasmorskyi-mediamonks hmm https://github.com/realm/realm-kotlin-samples/tree/main/Bookshelf checks all the boxes (uses ProGaurd, model in multiplatform module and same Proguard rules …) I wonder if you can manage to reproduce the issue using the Bookshelf as a starting base (i.e copy your model from the production app into it for instance) ?
