I'm facing a problem for over 3 days now and I can't solve. since I started to use Kotlin for Android,I stopped using "annotationProcessor" and started using "kapt", all things were working great with kapt until I started to build an Android Instant App, when I add "kapt" to any dependency like Glide or ButterKnife Gradle always displaying error that cound't find method kapt()
Could not find method kapt() for arguments [com.github.bumptech.glide:compiler:4.7.1] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.
Here are my project Gradle files
Project gradle file
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = '1.2.71'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
app module gradle file
apply plugin: 'com.android.application'

}
instantapp gradle file
apply plugin: 'com.android.instantapp'

implementation project(':base')
}
==========
Solved
by adding kotlin-android plugin to the base module
apply plugin: 'kotlin-android'
In my case,I was missing
apply plugin: 'kotlin-kapt'
Hope it helps someone as blind as me.
