Unresolved references of buildSrc kotlin constants after migration to gradle kotlin dsl

I´m trying to migrate my android project to using gradle kotlin dsl, replacing all build.gradle files with build.gradle.kts files and using kotlin there. Already before, I used to have a kotlin file containing object elements with library and version constants (in buildSrc -> src -> main -> kotlin), like:

object Versions {
    const val anyLibVersion = "1.0.0"
}

object Lib {
    const val anyLib = "x:y:${Versions.anyLibVersion}"
}

In build.gradle files, I can access these constants without problems, but as soon as I switch them to build.gradle.kts, it cannot resolve them anymore. Any explaination for that?

Does NOT treat the buildSrc directory as an module in settings.gradle.kts (.)

Precompiled script plugins.

Then for apply from in Kotlin DSL, you should use plugins {}

build.gradle.kts (X:buildSrc)

plugins {
    `java-gradle-plugin`
    `kotlin-dsl`
    `kotlin-dsl-precompiled-script-plugins`
}

repositories {
    mavenCentral()
}

Precondition

buildSrc/src/resources/META-INF/gradlePlugins/some-package-id.properties file:

implementation-class=gradlePlugins.android.AndroidLibraryPlugin

buildSrc/src/main/kotlin/gradlePlugins/android/AndroidLibraryPlugin.kt

Pay attention to the package of implementation-class will be "some-package-id"

package gradlePlugins.android

import org.gradle.api.Plugin
import org.gradle.api.Project

class AndroidLibraryPlugin : Plugin<Project> {

    override fun apply(project: Project) {
        project.configurePlugins()
        project.configureAndroid()
        project.configureDependencies()
    }

}

Consume the plugin:

Check that "some-package-id" will be the file name of some-package-id.properties

feature.gradle.kts

plugins {
    id("some-package-id")
}

You can fix it by completely removing the android {} block, doing a Gradle sync, and then adding the code block back.

What you'd typically have is following in buildSrc/build.gradle.kts

import org.gradle.kotlin.dsl.`kotlin-dsl`

repositories {
    jcenter()
}

plugins {
    `kotlin-dsl`
}

and then have your versions/dependencies in say buildSrc/src/main/java/Dependencies.kt
