Use the <modified> selector and you´ll only get files which content has changed.
Otherwise usually only the timestamp is checked (in <copy> e.g.)
>I would like to stop distribution if no files have been changed.

01: <target name="-deploy.check">
02: <fileset id="fs" dir="dir">
03: <modified/>
04: </fileset>
05: <pathconvert property="changedFiles"
06: refid="fs"
07: setonempty="false"/>
08: </target>
09:
10: <target name="deploy"
11: depends="-deploy.check"
12: if="changedFiles">
13: <!-- deploy -->
14: </target>
01: use a leading '-' so the user cant invoke it from the command line
03: check against the files content; if the timestamp is enough, dont use this
for better performance
07: important for line 12
11: perform the first target before (and before if/unless check)
12: only execute this target, if a property "changedFiles" is set - to some
value
(e.g. "false" or "true" or "file1,file2")
