If you are trying to use the SDK quickstart, I didnt get that to work either.
If you start from the Project quickstart: http://udig.refractions.net/confluence/display/UDIG/Project+Quickstart
You can then build the tool as described in http://udig.refractions.net/docs/BasicToolTutorial.pdf
 
You can go to IRC on the freenode server at the #udig channel. That worked real well for me when I was in trouble J

Emne: Re: [udig-devel] Plugins
 
 
I'm creating the plugin explained in BasisToolTutorial.pdf (Distance Tool). When I have to implement the ModalTool I can't locate this class: net.refractions.udig.project.ui.tool.AbstractModalTool.
I send you the printscreen of my problem. I don't know what I have to do. Import more classes? Configure something in Eclipse to search that class?
