'kapt.generatestubs' Is Not Used By The 'kotlin-kapt' Plugin

I recently updated from Android Studio 2.3 to 3.0, and kotlin 1.1.4 to 1.1.51. Now I'm seeing this message in my gradle console: 'kapt.generateStubs' is not used by the 'kotlin-ka

Solution 1:

It is completely safe to remove kapt { generateStubs = true }. It was originally used by kapt1, which is deprecated now.

Some docs about kapt: https://kotlinlang.org/docs/reference/kapt.html

Solution 2:

You should apply the kotlin-kapt plugin in your build.gradle file and remove the generateStubs = true

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
