When using the configuration option greenscript.minimize=true with Greenscript, all CSS url resources becomes wrong. For example, with jQuery UI,
.ui-widget-content { border: 1px solid #dddddd; background: #eeeeee url(images/ui-bg_highlight-soft_100_eeeeee_1x100.png) 50% top repeat-x; color: #333333; }
will look for images/ui-bg_highlight-soft_100_eeeeee_1x100.png under the gs folder, and will not find it, because the resources are under styles/themes/lightness (for example).
One obvious solution would be to manually replace all relative paths to absolute paths. But is there another (better) solution (not having to modify the original CSS files)?
Yes, this is a problem with current greenscript implementation. The fix should be released in later versions.
For your specific case, say jquery-ui, I recommend you to use CDN delivered css to avoid this issue. E.g. #{greenscript.css 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.0/themes/smoothness/jquery-ui.css' /}
