Re: Programmatically create a fileset and reference

Sure does, filelist accepts a set of files delimited by a space... So
when a path has a space it doesnt behave. Have used ant-contrib plenty
of times in the past, buts that not an option. The kicker is this isnt
a normal ant environment, but actually all the build files, etc are in a
jar when they are executed. Although I havent tried ant-contrib, this
environment causes problems with similiar tasks ant-call, ant, etc.
