title: How to inherit unmanaged dependencies in submodules in sbt?
body: <p>I have a project which looks like this, using sbt 0.13.2:</p>
  
  <pre><code>base
   - project
     - Build.scala
     - plugins.sbt
   - lib
     - unmanaged jar #1
     - unmanaged jar #2
   - core
      - src
        - .......
   - clp
      - src 
        - .......
   - server
      - src
        - ......
  </code></pre>
  
  <p>where <code>core</code> contains common code and <code>clp</code> and <code>server</code> are two related projects which both depend on <code>core</code>.</p>
  
  <p>I'm trying to find the right mojo in <code>Build.scala</code> such that all three of these modules depend on <code>base/lib</code>. Currently I'm cheating by using a symlink'd <code>lib</code> dir in each of the modules, but I'd like to do it automatically without the symlinks.</p>
  
  <p>Here's an example of <code>Build.scala</code> file - how should I modify this to make the dependencies work?</p>
  
  <pre><code>import sbt._
  import Keys._
  
  object RootBuild extends Build {
    lazy val buildSettings = Defaults.defaultSettings ++ Seq(
      scalaVersion := "2.11.1",
      unmanagedBase := baseDirectory.value / "lib"
    )
  
    lazy val standardSettings = buildSettings ++ Seq(
      libraryDependencies ++= Seq(
        "org.scalatest" % "scalatest_2.11" % "2.1.6" % "test",
        "org.testng" % "testng" % "6.8.8"
      )
    )
  
    lazy val Projects = Seq(root, core, clp)
  
    lazy val root = Project("root", file("."), settings=standardSettings) aggregate(core, clp)
    lazy val core = Project("core", file("core"), settings=standardSettings)
    lazy val clp = Project("clp", file("clp"), settings=standardSettings) dependsOn core
    lazy val server = Project("server", file("server"), settings=standardSettings) depensOn core
  }
  </code></pre>
