How to attach sources to SBT managed dependencies in Scala IDE?

Question

I'm using Scala IDE 2.0.1 and SBT 0.11.2 to start with Akka 2.0.1. My build.sbt looks like this:

name := "akka"

version := "0.1"

scalaVersion := "2.9.2"

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"

libraryDependencies += "com.typesafe.akka" % "akka-actor" % "2.0.1"

As you can see, there's nothing spectacular.

Now how can I tell Eclipse to use the artifact with the sources classifier for the akka-actor library?

In SBT, I can use update-classifiers to download sources and Javadocs to the Ivy repository, but even if I do this before running the eclipse command from the sbteclipse plugin then Eclipse still does not know the sources. Of course, I could do this manually, but this doesn't scale well for more libraries.

I have also tried to use the IvyDE plugin with the deliver-local command. While this integrates the dependency management, it doesn't seem to help with the sources.

Any clues?

Edit: This is the ivy.xml generated from deliver-local:

<?xml version="1.0" encoding="UTF-8"?>

    <exclude org="org.scala-lang" module="scala-library" artifact="*" type="jar" ext="*" matcher="exact"/>
    <exclude org="org.scala-lang" module="scala-compiler" artifact="*" type="jar" ext="*" matcher="exact"/>

    <override org="org.scala-lang" module="scala-compiler" matcher="exact" rev="2.9.2"/>
</dependencies>
</ivy-module>

I'm new to Ivy, so this doesn't tell me much. I just figure that it mentions sources and javadocs, but somehow the IvyDE doesn't pick it up.

You can put

EclipseKeys.withSource := true

to your build.sbt, which lets sbteclipse download all sources and makes them accessible within Eclipse. Note, this will download all sources from all configured dependencies. I have no idea how to tell sbt to download only the sources for single dependencies.
