Hello,
Due to the overhead of having to maintain Gremlin-Scala and for its lack of evolution, we have moved Gremlin-Scala to the Tinkubator.
Note, that you can successfully build the project from the Tinkubator.
While we plan to support more JVM languages, we will only do so if the there is consistent development on the port. As such, Gremlin is still packaged in the "language agnostic" manner with Gremlin-Groovy and Gremlin-Java being the two language deployed with Gremlin.
This update has been pushed to GitHub and deployed to Sonatype Maven repo. Finally, the Gremlin documentation has been updated to remove the Gremlin Scala references/instructions.
Apologies if this causes any problems for anyone using Gremlin Scala.
Good luck!,
Marko.
