Any reason when you do not have copy relative to workspace? Or copy from absoluate path? 

It is pretty annoying having to play around with trying to copy files from other job in the workspace.

Also suggest that you change "default excludes" to something that is more readable for naive users, like "default excludes (which will include .git, .sn  ... see http://ant.apache.org/manual/dirtasks.html#defaultexcludes")
