David Smiley commented on SOLR-2586:
------------------------------------
bq. But i see you only targeting empty directories, which cause little
confusion at all.
It's what had my attention at the time due to combination of writing about them
and working with git. The other possible improvements you mention sound good to
me too.
I'll create a separate issue for git for .gitignore. But I wanted to first
figure out here if those empty directories needed to be there in the first
place. "work" does, "log"... ? Arguably not. I think a little tolerance in
the ant "example" target to needing to create these directories is preferable
to adding special hidden files, which always seem to be a bit of a kluge.

> Key: SOLR-2586
> URL: https://issues.apache.org/jira/browse/SOLR-2586
> Project: Solr
> Issue Type: Improvement
> Components: Build
> Reporter: David Smiley
> Priority: Minor
>
> Firstly, what prompted this issue was me wanting to use a git solr mirror but
> finding that git's lack of empty-directory support made the "example" ant
> task fail. This task requires examples/work to be in place so that it can
> delete its contents. Fixing this was a simple matter of adding:
> {code:xml}
> <mkdir dir="${example}/work" /><!-- in case not there -->
> {code}
> Right before the delete task.
> But then it occurred to me, why even have a "work" directory since Jetty will
> apparently use a temp directory instead. -- try for yourself (stdout snippet):
> bq. 2011-06-11 00:51:26.177:INFO::Extract
> file:/SmileyDev/Search/lucene-solr/solr/example/webapps/solr.war to
> /var/folders/zo/zoQJvqc9E0076p0THiri+k+++TI/-Tmp-/Jetty_0_0_0_0_8983_solr.war__solr__k1kf17/webapp
> On my Mac, this same directory was used for multiple runs, so somehow Jetty
> or the VM figures out how to reuse it.
> Since this "example" setup isn't a *real* installation -- it's just for
> demonstration, arguably it should not contain what it doesn't need.
> Likewise, perhaps the empty example/logs directory should be deleted. It's
> not used by default any way.
