In order to resolve a lib you should add a resolver::
resolvers += sbt.Resolver.bintrayRepo("denigma", "denigma-releases") //add resolver libraryDependencies += "org.denigma" %%% "threejs-facade" % "0.0.77-0.1.8" //add dependency
You can see an example in preview subproject.
To run preview:
sbt //to opens sbt console re-start //Use this command **instead of** run to run the app Open localhost:5552 to see the result
