I'm a bit confused on the newest annotation processor introduce in Android and related to Kotlin which is "kapt" Question :

  1. What is kapt ( kotlin annotation processing tool) and its uses case? Or what does apply plugin: 'kotlin-kapt' help us within our android project.

  2. Difference between Kapt and annotationProcessor in Gradle

    Example:-

    //Dagger with annotationProcessor vs with kapt

    annotationProcessor libraries.daggerCompiler

    kapt "androidx.room:room-compiler:$rootProject.roomVersion"

android-gradle-plugin kotlin android-studio gradle android
