defaulting jaxws version to 2.1, change it if you really want 2.1.  for now, though, java is still on SE 6 for a lot of computers, so this makes sense for now
couple of changes here, makes info logs a little more clearer
editring the parse wsdl task to exclude the input file, for some reason, it doesn't work if it is dynamic, have to figure out a better solution, did change the destionation Output Directory, and it works fine.
editing the plugin configuration to a more generic interface class Task, instead of the lower level specific classes i.e WsdlNameTask, and adding the configuration for the destinationDirectory as the OutputDirectory
adding an examples folder, so you can see the plugin in action
