Currently jspwiki 'builds' its javascript and css files from ant. Building here simply means compression by means of the YUI compressors. The sources are large concatenations of chunks of javascript and css.
This article ( http://raibledesigns.com/rd/entry/javascript_and_css_concatenation) showed me some light-weight, alternative approach for building the js/css on-the-fly, with some additional features as bonus. It will allow to break the js into logical chunks, and improve source management. The same can be applied to the css file. See project home page at http://code.google.com/p/wro4j/ WDYT ? dirk
