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

intellij-idea, sbt, scala

Solution

In the IntelliJ Idea window of your project, got to File >> Project structure >> Libraries. After clicking that Libraries option, two panes will show up. At the top of the left-most pane, click the green "+" button.

Problem

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.
