> Gradle files (a Kotlin alternative is coming)
Gradle's been able to use Kotlin for build files since Gradle 3.0 which was released last year.
For Jenkins, only a subset of Apache Groovy can be used. None of the functional methods will work when used.
Grails 2.x is still around, but virtually no-one's converting their projects to version 3, or starting new Grails projects in version 3.
Groovy development has come to a standstill, and even contributions from outside developers just sit there, such as the new Antlr 4-based parser which someone contributed a whole year ago.
Kotlin has its own build system - Kobalt.

We've stuck with Grails for a few years now and I still prefer it over vanilla Spring Boot. Things like JSON views and GORM are still really nice to have.
I don't have a good read on how popular Grails is anymore. I liked it a lot in the past but I don't need it anymore with Kotlin and Spring Boot.
