I am trying to include one external sbt sub project. Please find below build.sbt snippet :-
lazy val root = (project in file(".")).dependsOn( ProjectRef( file("../../ScalaWork/ActorCore"), "ac" ) )
Below is the error that I am getting :-
[error] C:\git\Test\project\build.scala:49: not enough arguments for method apply: (id: String, base: java.io.File, aggregate: => Seq[sbt.ProjectReference], dependencies: => Seq[sbt.ClasspathDep[sbt.ProjectReference]], delegates: => Seq[sbt.ProjectReference], settings : => Seq[sbt.Def.Setting[_]], configurations: Seq[sbt.Configuration], auto: sbt.AddSettings)sbt.Project in object Project.
What is the correct syntax to include external sbt project.
