Any help on this. Stuck with the above error and unable to proceed

Looks like you are not transforming the realm model classes. If you don't apply our plugin you will have to register the transformer yourself.

Adding the realm-transformer jar file to libs doesn't help here? Is there any way to apply the plugin using jar file. Earlier I used android.registerTransform(new RealmTransformer(rootProject)) to register but in Gradle 8 android.registerTransform is deprecated.

I have tried using

import io.realm.transformer.RealmTransformerKt RealmTransformerKt.registerRealmTransformerTask(rootProject)

to register the RealmTransformer in the build.gradle file, however getting below error while trying to build it

Caused by: org.gradle.api.UnknownDomainObjectException: Extension of type 'AndroidComponentsExtension' does not exist. Currently registered extension types: [ExtraPropertiesExtension, KtlintExtension] at org.gradle.internal.extensibility.ExtensionsStorage.getHolderByType(ExtensionsStorage.java:88) at org.gradle.internal.extensibility.ExtensionsStorage.getByType(ExtensionsStorage.java:74) at org.gradle.internal.extensibility.DefaultConvention.getByType(DefaultConvention.java:160) at org.gradle.internal.extensibility.DefaultConvention.getByType(DefaultConvention.java:155) at io.realm.transformer.RealmTransformerKt.registerRealmTransformerTask(RealmTransformer.kt:88) at io.realm.transformer.RealmTransformerKt$registerRealmTransformerTask.call(Unknown Source)

Let me know if I missed anything here
