Is it just impossible for JavaHL to expose this, or is it a matter of
"nobody needed this until now, and someone just needs to do it", in
which case maybe I should ask about this on the svn-dev mailinglist
(or file a feature request there)?

Thanks, that's good to know. Unfortunately, AFAICS svnant does not
expose config-dir. So I filed a feature request for this:

Hm, thanks for the suggestion, but I'm afraid I can't use that
workaround, because it's not "thread-safe". I might be running two
builds for two different applications at the same time on this server.

Thanks,
