I'm not Ant expert, but a look in the manual suggests that you should try:=


<available file=3D"../jarbundler-0.5/bin/jarbundler-0.5.jar" property=3D"j=
arbundler"/>
<fail unless=3D"jarbundler" message=3D"=B4*** your preffered error message=
 ***"/>

I.e. you should use <available> to determine if the jar file exists.

Hope it helps :-)
