Thanks, that almost got me to where I wanted to be. One problem that
I think I've surmounted is the need for a file that's older than any
existing file:
<target name="externaljars">
<touch file="oldFile" millis="0"/>
<uptodate property="externalJars.available" targetfile="oldFile">
<srcfiles refid="requiredJars"/>
</uptodate>
<delete file="oldFile"/>
<fail unless="externalJars.available"/>
</target>
The reason I say "I think" is that I haven't managed to make the
requiredJars FileSet. Problem is, the required files come from
several different directories, some from within the build space, some
from without. It was easy to make a ClassPath with them, but that's
not a usable argument for <srcfiles> in <uptodate> (but I need it
elsewhere). Reading the FileSet docs, I don't see a way to make a
FileSet without setting a dir - even if all I want to do is include
some other filesets. Trying with dir="/" and then absolute paths
(prolly a problem on non-Unix systems) led to this interesting error:

So your approach requires a FileSet, but I can only make FileList or
ClassPath structures for my list of files. Yes, I could kludge around
it by testing on several different FileSets in the existence test, but
surely there's a more structured way than that?
Thanks,
