Relocate/rename WebContent?

I get the error below when trying to compile my widgetset using the Eclipse plugin (button on toolbar). My project is a dynamic web project, but I’ve changed the location and name of the WebContent folder. Is there a way to tell Vaadin to look for a directory other than the WebContent folder?
