Netbeans 6.8 JME3 Installation

I am following this tutorial:

However, when i try to “resolve referencing problems” and add the SevenZip project, there isn’t an option to add “projects”, only “jars/folders”…So I tried building the SevenZip project and it builds fine, and I added the jar generated from that build to the “resolve referencing problems” window, and it didn’t fix my problem…

I’m stumped here. Can anyone help me?
