Subject RE: Can a jar fileset/zipfileset refer to a nonexistent directory?
Date Fri, 02 Aug 2002 05:11:41 GMT
Scott,

you are correct - A FileSet will break if the directory does not exist.
If you feel strongly about this bug (as I do), then please cast a vote for
it - see link

"FileSet and DirSet break if the directory does not exist"
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=11270


To get around your problem, you can create the directory (as you have
surmised).
Or you can skip targets containing the fileset by using a combination of the
Available task and depends - very clunky.
Or specify a fileset whose directory is known to exist and use the
<include><exclude> to filter the files - may inclde relative paths that are
not suitable.

I sugest option 1, and help get it fixed for Ant 1.6 :-)
