'kapt.generateStubs' is not used by the 'kotlin-kapt' plugin

Question

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-kapt' plugin

I have this in my build.gradle to get my project working with some libraries using annotation processing:

kapt { generateStubs = true }

Is the generateStubs line no longer needed and is it safe to remove? Or is there another action I should take to remove the warning message above?

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'
