Unresolved reference: AndroidBaseExtension in gradle plugin

Question

I am trying to create custom gradle plugin by this article https://quickbirdstudios.com/blog/gradle-kotlin-buildsrc-plugin-android/, and i stuck on this error. What i am doing wrong?

settings.gradle.kts

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}
rootProject.name = "qweqwe"
include(":app")

project_build.gradle.kts

plugins {
    id("com.android.application") apply false
    id("com.android.library") apply false
    kotlin("android")
}

tasks.register("clean", Delete::class){
    delete(rootProject.buildDir)
}
