How to add Jar libraries to an IntelliJ Idea SBT Scala project?

Question

I've created an IntelliJ Idea SBT Scala project like Heiko Seeberger's article describes.

I'd like to add a Jar library (joda-time) to use in this project. How to do this? Simply putting them into project's /lib does not help. If I right-click "External libraries" in Idea's project tree, "New >" is greyed.
