What maven dependency for kotlin cucumber?

I want to use the kotlin native step definitions like:

package cucumber.runtime.kotlin.test;
...
class LambdaStepdefs : En {
init {
    Before { scenario: Scenario ->
        assertNotSame(this, lastInstance)
        lastInstance = this
    }

    Given("^this data table:$") { peopleTable: DataTable ->
        val people = peopleTable.asList(Person::class.java)
        assertEquals("Aslak", people[0].first)
        assertEquals("Hellesøy", people[0].last)
    }

Where Given takes a function and is not an annotation. I do not want to use the Java-style like @Given("blabla") void blabla() { ... }.

I tried to import the package from the example:

package vc.capper.cutest;

import cucumber.runtime.kotlin.test

class SomeStepDefs
{
    Given("blabla") {
    }
}

But the package kotlin can not be found in cucumber.runtime.

I thought the io.cucumber:cucumber-jvm (artifact)[https://github.com/cucumber/cucumber-jvm/blob/master/pom.xml] comes with cucumber-kotlin-java8, but it either does not or it does not contain said Given.

This is an excerpt from my pom.xml -- somethign is missing, I guess, but what?

Prelude:

<properties>
  <java.version>1.8</java.version>
  <kotlin.version>1.1.2-2</kotlin.version>
  <spring-boot.version>1.5.7.RELEASE</spring-boot.version>
  <cucumber.version>2.0.1</cucumber.version>
</properties>

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
  ...
</dependencyManagement>

Dependencies:

<dependencies>
  <dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-jvm</artifactId>
    <version>${cucumber.version}</version>
    <type>pom</type>
  </dependency>

  <dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-spring</artifactId>
    <version>${cucumber.version}</version>
  </dependency>
  <dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-junit</artifactId>
    <version>${cucumber.version}</version>
    <scope>test</scope>
  </dependency>

  <dependency>
    <groupId>org.jetbrains.kotlin</groupId>
    <artifactId>kotlin-stdlib-jre8</artifactId>
    <version>${kotlin.version}</version>
  </dependency>

  ...
</dependencies>

Update and clarification:

The packages that seem to be missing are cucumber.runtime.kotlin and cucumber.api.java8.En as you can see from the IntelliJ screenshot:

Also you can see the list of actual dependencies the project uses:

Change <artifactId>cucumber-jvm</artifactId> to <artifactId>cucumber-java8</artifactId> to use lambda style definitions.

Note there currently is no native Kotlin implementation of cucumber.

Also, the cucumber-kotlin-java8 you are referring to is an example of how to use Cucumber-java8 with Kotlin.

In addition, you'll need to extend the En interface.

It looks like that Given is not a Kotlin specific DSL / method. It is a part of cucumber.api.java8.En. All you have to do is to extend your class from it:

package vc.capper.cutest;

import cucumber.runtime.kotlin.test
import cucumber.api.java8.En

class SomeStepDefs : En {
    Given("blabla") {
        ...
    }
}
