Fileset Evaluation
If I define a fileset via a patternset and a id like that:
<patternset id="dopecopy.configpattern.kunde">
<exclude name="javahelp/**"/>
<exclude name="imagesText/**"/>
<exclude name="dcpcall.xml"/>
<exclude name="mffafp.pro"/>
</patternset>
<fileset id="dopecopy.configfiles.kunde" dir="${dope.configdir.kunde}">
<patternset refid="dopecopy.configpattern.kunde"></patternset>
</fileset>
And now I add another file to the fileset-dir: ${dope.configdir.kunde}
E.g. like that:
<jar destfile="${dope.configdir.kunde}/editorHelp.jar">
<fileset dir="${dope.configdir.kunde}/javahelp/editor" />
</jar>
Will editorHelp.jar be copied or not?
<copy todir="${dope.target.dir}/config">
<fileset refid="dopecopy.configfiles.kunde" />
</copy>
Is editorHelp.jar part of the fileset, even if it did not exist, when I created the fileset?
Why?
In my case, I think it was part of the fileset and I don't understand why!
In other words:
When will filesets be evaluated? Waht are the rules?

Actually IIRC FileSet and DirSet are (by virtue of
their common parent class) implemented such that each
use re-scans the filesystem, except in the rare event
that the DirectoryScanner is requested concurrently
from separate threads. It would probably be pretty
easy to concoct a "frozen" ResourceCollection, but as
a workaround wrapping the fileset in a <union> and
forcing an evaluation with e.g. <pathconvert> or
<resourcecount>, then relying on its cache=true
default setting to cache those results...

They're generally evaluated the first time theyre a used, and (probably)
not re-evaluated.
to get reevaluation in, dont cache the fileset but explicitly redeclare
it again.
