Configuration closure in kotlin, build.gradle.kts

Help/Discuss
#1

jgitver, https://github.com/jgitver/gradle-jgitver-plugin, has in its configuration the option to use a repeatable closure:

jgitver {
  policy {                         repeatable closure
    pattern string              (regexp with capturing group)
    transformations array       (array of string)
  }
}

how would one write this in kotlin, or the plugin needs to be adjusted so it works?
