What is the difference between kapt and implementation in Gradle when declaring dependencies and when should one be used over another?

Example:

//Room Components
implementation "androidx.room:room-runtime:$rootProject.roomVersion"
kapt "androidx.room:room-compiler:$rootProject.roomVersion"

// dagger
implementation "com.google.dagger:dagger:$rootProject.ext.daggerVersion"
kapt "com.google.dagger:dagger-android processor:$rootProject.ext.daggerVersion"

  • `kapt` and `implementation` are not analogous.

In short: implementation and kapt are not related directly

When it comes to kotlin, you use kapt where Java uses annotationProcessor.

Which one to use? Depends on how the lib works
