I want to be able to support "skinning" of web applications like this: - a "web/default" directory contains default resources such as (HTML, images, JSPs, etc) - a "web/skin_x" directory contains overrides for some of the default resources, to implement an alternative look&feel. Now I want to create a directory "web/resolved" that contains web/default with the skin applied. So say I have web/default/xxx.html web/default/yyy.html web/skin_x/xxx.html I want web/resolved/xxx.html = web/skin_x/xxx.html web/resolved/yyy.html = web/default/yyy.html This works: <copy todir="web/resolved"> <fileset dir="web/default" /> </copy> <copy todir="web/resolved" overwrite="yes"> <fileset dir="web/skin_x" /> </copy> But I'd really like to be able to do it without needing the overwrite="yes". That is, I only want to do the copy when something changes. Can I set up some kind of "search-path" for the copy? -- Mike
