Getting a dependency list in a custom plugin

[EJ Ciramella]

Hello all - I have what seems like a simple question that's got me
stumped at the moment.
 
Is there a way to iterate over the dependencies in a particular project
inside a custom plugin?
 
I keep wanting to do something like:
 
     ArrayList deps = (ArrayList) proj.getDependencies();
     for(int x = 0; x < deps.size(); x++)
     {
      getLog().info("--> "+deps.get(x));
     }
 
Just for testing purposes, but at runtime, I keep getting this
stacktrace:
 
java.lang.NoClassDefFoundError: org/apache/maven/project/Model
        at org.apache.maven.project.Project.<init>(Project.java:120)

I get the feeling I'm not using the right Project class.
 
Any suggestions would be really helpful.
