title: Maven & yui-compressor Plugin issues
body: <p>I'm using the yui-compressor plugin for maven and can't seem to get it to compress. The appending of all js files works fine. It doesn't remove comments, line breaks and it doesn't minify the js (i.e. turn var myVar into var a). Is there something wrong with my configuration?</p>
