Hoss Man commented on LUCENE-4115:
----------------------------------
I'm not sure i'm following you.
right now, we know that when you run "ant test" (or "java -jar start.jar" in
solr) you getting the exact same classpath and set of jars as someone who
downloads a binary dist you might build from your checkout -- because the
classpath you are using comes from the lib dirs, built by ivy. there is only
one places jars are "copied" from the ivy cache to the lib dir(s).
if instead we have ant <classpath/> declarations that use ivy features to build
up classpaths pointed directly at jars in the ivy cache, and independently we
have <copy> directives building up the lib/ dirs that make it into the binary
dists, then isn't there a risk that (overtime) those will diverge in a way we
might not notice because all the testing will only be done with the ivy
generated classpaths?
(maybe i'm wrong ... maybe the ivy classpath stuff works diff then i understand
... i'm just raising it as a potential concern)
> JAR resolution/ cleanup should be done automatically for ant clean/ eclipse/

> Project: Lucene - Java
> Issue Type: Task
> Reporter: Dawid Weiss
> Assignee: Dawid Weiss
> Priority: Trivial
> Fix For: 4.0, 5.0

> Attachments: LUCENE-4111.patch

>
> I think we should add the following target deps:
> ant clean [depends on] clean-jars
> ant resolve [depends on] clean-jars
> ant eclipse [depends on] resolve, clean-jars
> ant idea [depends on] resolve, clean-jars
> This eliminates the need to remember about cleaning up stale jars which users
> complain about (and I think they're right about it). The overhead will be
> minimal since resolve is only going to copy jars from cache. Eclipse won't
> have a problem with updated JARs if they end up at the same location.
> If there are no objections I will fix this in a few hours.
