Gradle Kotlin DSL: Extract contents from dependency

Question

How do I convert the following snippet (based on the one by Peter Niederwieser) to Kotlin?

configurations {
    assets
}
dependencies {
    assets 'somegroup:someArtifact:someVersion'
}
task extractApi(type: Sync) {
    dependsOn configurations.assets

    from { // use of closure defers evaluation until execution time
        configurations.assets.collect { zipTree(it) }
    }
    into "$buildDir/assets/"
}

Answer 1

I haven't experience with the Kotlin DSL, but apparently the extractApi task could be re-written as

val assets by configurations.creating

dependencies {
    assets("somegroup", "someArtifact", "someVersion")
}

tasks {
    val extractApi by creating(Sync::class) {
        dependsOn(assets)

        from(assets.map {
            zipTree(it)
        })

        into("$buildDir/api/")
    }
}
