Not sure, you might've tried it already, but saying it just in case, there are two useful tasks if you want to canonicalize the path:
<pathconvert targetos="win" property="FLASHPLAYER_DEBUGGER.win"> <path location="${FLASHPLAYER_DEBUGGER}/../lib/player/ 11.1/FlashPlayerDebugger.exe"/> </pathconvert> Or <dirname property="FLASHPLAYER_DEBUGGER.dir" file="${FLASHPLAYER_DEBUGGER} /../lib/player/11.1/FlashPlayerDebugger.exe"> I also think that the first one would reverse the slashes into "Windows mode"... actually, from the time I built on Windows I can remember that Windows will not handle a situation when there are both kinds of slashes - which you might be seeing. So it would be better to use <pathconvert/> because it would canonicalize the pathnames for every system. Best. Oleg
