Scala IDE 4.1 and SBT

Question

We have a project that uses Scala macros. Scala IDE 4.1 supports Scopes to ease compilation of projects with macros. However, when I use sbt eclipse, the generated project does not show macros as a source folder and does not create separate outputs for each source folder. Is this a missing feature in SBT? Is there any workaround?

My build.sbt file looks like this:

name in ThisBuild := "Test"

organization in ThisBuild := "org.test"

version in ThisBuild := "0.1.0"

scalaVersion in ThisBuild := "2.11.6"

libraryDependencies ++= Seq(
    "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test",
    "junit" % "junit" % "4.11"
)
