<target name="isAvailable">
<available file="yourFile.txt"
property="yourFile.txt.available"/>
</target>
<target name="copy" depends="isAvailable"
if="yourFile.txt.available">
<copy file="yourFile.txt" tofile="yourFile.txt.backup"/>
</target>
Insert these two targets to your build.xml.
call
> ant copy
it will only do a backup if the property yourFile.txt.available
is set. the Property yourFile.txt.available will be set via
target isAvailable (if the file yourFile.txt is present)
Hope that helps. Works fine foe me
