Realm Transformer Output Missing During Android Instrumented Test

How frequently does the bug occur?

Always

Description

This is related to #2936 and #3030

After upgrading to Gradle 7, our build is now issuing a warning about a deprecated feature (the AGP Transformer API). It seems that newer versions have been released to address this however our app is not currently able to support realm 10-x versions.

When running Android instrumented tests a ClassCastException is being thrown at runtime. Several attempts were made to resolve this, like adding kotlin-kapt before realm-android Gradle plugin. The exception only occurs during instrumentation tests.

The output of the realm transformer is being generated to the app/build/intermediates/transforms. Yet the final APK being ran does not contain the generated source.

Stacktrace & log output

java.lang.ClassCastException: my.package.MyRealmObject cannot be cast to io.realm.my_package_MyRealmObjectProxyInterface
