kotlin-kapt plugin with version catalogs

Question

I have migrated my build to use version catalogs. I have removed the following from my build.gradle

plugins {
id 'kotlin-android'
id 'kotlin-kapt'
}

and

kapt "androidx.room:room-compiler:$room_version"
annotationProcessor "androidx.room:room-compiler:$room_version"

kapt "com.google.dagger:hilt-compiler:$hilt_version"

now I am getting

warning: The following options were not recognized by any processor: 
'[dagger.hilt.internal.useAggregatingRootProcessor, room.schemaLocation, 
dagger.fastInit, dagger.hilt.android.internal.disableAndroidSuperclassValidation, 
dagger.hilt.android.internal.projectType]'

1 warning

and

A failure occurred while executing 
com.android.build.gradle.internal.tasks.MergeJavaResWorkAction
 > 2 files found with path 'META-INF/gradle/incremental.annotation.processors' from 
 inputs:
  - /.gradle/caches/transforms-

   - /.gradle/caches/transforms- 
 3/f1c91d9e7fbd546100043f736678c477/transformed/jetified-dagger-compiler-2.45.jar

Now I am wondering how to add kotlin-kapt as a plugin to the version catalogs. Or how do I use the annotationProcessor with version catalogs?
