Nowadays I would look at Kotlin, if you really need Java's slowness—er, features—in a shinier package. I still use Groovy to write quick scripts or cron jobs that need to use Java libraries. Basically the Bash or Python of the JVM. Otherwise there are much better choices. I've never worked on an "enterprise system, not web based," so I'm not sure what it is, but it sounds important and large. I wouldn't write such a thing in Groovy, or any other dynamically typed language: one misspelled variable and you have a runtime error waiting for you. (I wouldn't write such things in Java either: one missing null check and you have a runtime NPE waiting for you. But alas, the industry thinks otherwise.) PS. Whatever you do, stay away from Grails. I've never seen such a bug-ridden, slow and crappy piece of junk in my entire career. And when I say bug, I mean a running production system suddenly starting to omit all WHERE clauses from all SQL queries, out of the blue. The app still working properly, but customers seeing the data of all other customers. I'm not joking.

Apache Groovy's worked quite well as the "Bash of the JVM", though other JVM languages have been moving into that space lately. Clojure's also quite good for running tests -- its macros can easily eliminate clutter in repetitive tests. Kotlin's been chosen by Gradleware as their preferred language for writing Gradle plugins and build scripts. And Scala doesn't really need glue code for tying its classes together because it can do that itself. Virtually no-one's ugraded Grails to version 3 since it came out over 2 years ago, or starting new projects with it. Groovy's adoption is dropping fast, e.g. it slipped out of Tiobe's top 50 a few months ago, and some robot running in Germany is responsible for most of its downloads.
