When trying to run a build.xml (see attached) from a Win XP command line (also from a Cygwin commandline), I receive an error messagebox from the "MS DOS 16-bit sub system" (sorry, the list server prohibited me from attaching an image of the msgbox because the attachment was too large). I believe that the environment property that I set in line 14 of build.xml is returning nothing and generating a null-pointer exception as a result. The build seems to fail while trying to load/execute the following line: <property environment="ncenv" /> The build.xml using the same tools, environment, and directory structure under linux. Any help beyond telling me to re-write my build.xml with static pathing would be greatly appreciated. Sincerely, Derek Bennett
