How to reference external sbt project from another sbt project?

Question

I have the following setup of a Scala application and a common core library: root

 -> /ApplicationA
   -> /project
     -> /build.sbt
 -> /CoreLi         


        

Answer 1

Since sbt 0.13, you may create multi-project definitions directly in .sbt without needing a Build.scala file.

So adding the following to ApplicationA/project/build.sbt would be sufficient.

lazy val core = RootProject(file("../CoreLibrary"))

val main = Project(id = "application", base = file(".")).dependsOn(core)
