title: Scala play sbt multi projects at same folder level
body: <p>I'm working on 2 projects in Eclipse on Windows. They're kept in their own separate folders. Their folders are located here: 
  W:\scala\eclipse\sdtcore
  W:\scala\eclipse\sdttools</p>
  
  <p>The development effort for these two projects are ongoing and therefore I haven't made JARs for them. I prefer to continue developing in Eclipse. </p>
  
  <p>What I'd like is to include these two projects / their source code in a Scala Play Play project. At the moment I've tried using Typesafe Activator to generate a Play project, but I simply cannot modify the build.sbt file in a satisfactory way which can get this to work. In time I'd also prefer developing in Eclipse, but for now I can live with a simple text editor (it seems somewhat buggy/not straightforward getting it to work in Eclipse - or IntelliJ for that matter). </p>
  
  <p>I'd prefer to keep my Play project in this folder for now: 
  W:\scala\practice\play</p>
  
  <p>I am somewhat new to both Play and SBT, but have gone through some tutorials regarding SBT and subprojects and got it work - however not with a project structure like the one described. Instead I've ran against the wall with error messages complaining that my subprojects to not belong to the root folder of the project. </p>
  
  <p>Can it be done? How should I go about? Simpliest, easiest course of action. </p>
