reloving dependencies from unneeded projects in depended builds

[drue]

I have a Build containing a Project that depends on another Project using ProjectRef from a different Build on Github that contains multiple Projects. The specific Project that I depend on is OK and has no unresolved dependencies so I can run the update and compile tasks without dependency errors. However, when I run the eclipse task, sbt is attempting to resolve dependencies from other projects I do not depend on in the same Build as the project I do depend on that happen to be broken, which leads to unresolved dependency errors and makes the eclipse task stop without producing the project files.

e.g.

 Build1 {
  val myProject = Project(...).dependsOn(ProjectRef(uri(...Build2Repo...), "dependedProject"))
}

then in the repo on github (not mine)

Build2 {
  val dependedProject = Project(...)
  val fooProject = Project(...).dependsOn(dependedProject)
  val barProject = Project(...).dependsOn(fooProject)
}

when I run eclipse task (but not update task) sbt is trying to resolve dependencies in fooProject and BarProject even though dependedProject does not depend on them and neither does my project.
