How can I change the ContextRoot that Maven Glassfish Plugin deploys to?

I'm deploying a webapp (WebApp.war, say) using the Maven Glassfish Plugin. Rather than it being deployed to http://localhost/WebApp I want it to be deployed to http://localhost/AnotherName - that is, I want to change the context root it's deployed to. I can't work out how to do this with the plugin, is it an option?
