Gradle translate groovy to kotlin for plugins

I currently have an init.gradle file which works fine:

initscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath("com.github.ben-manes:gradle-versions-plugin:+")
    }
}
allprojects {

    apply plugin: com.github.benmanes.gradle.versions.VersionsPlugin
}

Now I would like to move towards the kotlin DSL, as all other projects I am working on are moved over.

So I created this:

initscript {
  repositories {
    jcenter()
  }

  dependencies {
    classpath("com.github.ben-manes:gradle-versions-plugin:+")
  }
}
allprojects {
  apply(plugin = com.github.benmanes.gradle.versions.VersionsPlugin)
}

Unfortunately I get the following error:

Script compilation error:

  Line 11:   apply(plugin = com.github.benmanes.gradle.versions.VersionsPlugin)
                                                                ^ Classifier 'VersionsPlugin' does not have a companion object, and thus must be initialized here

when I try to put " around the plugin, I get the error:

* What went wrong:
Plugin with id 'com.github.benmanes.gradle.versions.VersionsPlugin' not found.

When I try

apply<VersionsPlugin>()

I get:

  Line 10: apply<VersionsPlugin>()
                 ^ Unresolved reference: VersionsPlugin

When I try:

apply(plugin = "com.github.ben-manes.versions")

I get:

* What went wrong:
Plugin with id 'com.github.ben-manes.versions' not found.

In the gradle documentation I just found a hint about how to initialize a new plugin, not how to add an existing plugin.

Anybody here who can help me?

There is a special Kotlin extension function for this

apply<VersionsPlugin>()

// or
apply(plugin = "com.github.ben-manes.versions")

UPDATE: The first option works well for me. The full content of the init.gradle.kts file:

import com.github.benmanes.gradle.versions.VersionsPlugin

initscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath("com.github.ben-manes:gradle-versions-plugin:+")
    }
}

allprojects {
    apply<VersionsPlugin>()
}

Usage: ./gradlew dependencyUpdates -I init.gradle.kts

The second option fails indeed, sorry. The reason is not clear to me.
