> It would be great if somehow we could smush Gradle and sbt together to build a best of all possible worlds build system for Scala

www.gradle.org/overview does say "The Gradle design is well-suited for creating another build script engine in JRuby or Jython. It just doesn't have the highest priority for us at the moment. We happily support any community effort to create additional build script engines."

I have looked at the Gradle source code and Groovy seems to be tightly entangled in it, and it would be difficult to get Gradle to use another DSL language. I'm also doubtful about what they say about happily supporting community effort to create other script engines. Based on my previous experience with the people behind Groovy, not only with regards to the Groovy++ fiasco of mid- to late-2011 but many times before, that line could easily mean "We're happy to hear about any community effort to create additional build script engines so we can scuttle your attempt before it gets very far."

> The simplicity of its syntax vs scala is a great point for Groovy though

Did you say Groovy's syntax is simple? The Gradle DSL is just a tiny subset of Groovy's grammar, see [1]. It's also still stuck on Antlr 2 because no-one wants to try upgrading it to Antlr 4. Scala was designed so its grammar would be light and the functionality residing in the libraries.
