EdgeType.DIRECTED not working

I recently figured out how to add the Jung libraries to eclipse, but now I ran into a new problem. I'm using the Jung tutorial and I can't seem to run the first tutorial, because the Eclipse IDE is saying that the .开发者_运维问答DIRECTED ,in the code, cannot be resolved or is not a field. How do I fix this?

edit: Yes, using that package worked! However, I'm surprised that the Eclipse IDE did not offer to import the package for me. Is this unusual?

Make sure to include all the required JUNG2 libraries into your Eclipse project. When you do that, Eclipse will give a few suggestions after you right-click on those yellow-underlined words. Choose the one(s) related to JUNG2 to remove the warning(s).

EgeType.DIRECTED must be imported from edu.uci.ics.jung.graph.util.EdgeType package which is under jung-graph-impl-2.0.1.jar
