It isn't. Gradle still ships with the slower Groovy 1.x, and Grails, altho it ships with Groovy 2.x, doesn't actually use any of the faster static-typing, presumably because it's still too buggy.
It would be nice if Gradle used Scala or Kotlin as its build language instead, but with a name like "GradleWare", I suspect someone from VMWare is pulling the strings to keep Gradle tied to Grails (and Groovy).
