How to reference third-party libraries, eg breeze, from eclipse, when working with Scala

Question

I have Eclipse, with eclipse-ide plugin installed, and with 'sbt' selected as the builder. I want to use a third-party library, specifically scala-breeze, and I'm not sure how to instruct eclipse/scala-ide to fetch and install this?

Answer 1

Add the breeze dependency via sbt, then run the sbt eclipse command to get everything configured. The command must be run each time something in the build changes.
