Hi, I've just published an article at http://wicketinaction.com/2014/07/build-resources-with-node.js/ explaining how to use Node.js based tools for building, watching and live reloading resources (LESS/SASS/JS/...) in your Maven based Wicket applications.
I hope you find it useful! Martin Grigorov Wicket Training and Consulting https://twitter.com/mtgrigorov
