Re: [jira] Commented: (IVY-704) In the ResolveReport class, add the possibility to filter the evicted module while getting the list of DownloadArtifact
Answering in ant-dev, because this might be a larger topic.

In fact I was assuming that in the list of artifact returned by a
retrieve task, there won't be any duplicate entry, even with different
version, because they will conflict.
I have a such ivy.xml on which I do a resolve for every conf on, and
then I have duplicate entries in IvyDE. And from the ivy reports,
there is effectively a configuration where the should-be-evicted
artifact is resolved without being evicted.
Then what does mean doing a single resolve on several conf. As you
explained, in the actual implementation it is just a aggregation of
several independent resolve tasks, each task on one conf. As a user I
would expect that a multi-conf retrieve will generate a coherent
classpath. It would be similar to creating a new conf, making it
depends on the confs I really want, and then doing a resolve on it.
(continuing thinking loudly)
But my conf maybe wrong in fact. Having two confs which produce two
same artifacts without the same version seems wrong. We can imagine
two different confs named withJetty5 and withJetty6. And of course
they should not be retrieved jointly.
Maybe Ivy should trigger a warn/error ? Or at least the ant task and
IvyDE ?

Finally it seems that it should be the user of the core API (ant task or
IvyDE) which should warn the end user, so yes the current API should stay the
same without trigerring a warn.
I will put it to IvyDE.

Configurations in Ivy are considered isolated. Resolving or retrieving
several confs at a time is only a shortcut for doing the same thing with
each conf at a time. I don't know if it's the best thing to do or not, but
at least it's consistent, and it works like that since the beginning. Any
time resolving several confs at a time has an impact this is considered a
bug and we fix it. So if you really want your confs to be resolved at once
and conflict management to occur between them, you need to create another
conf extending the others.
Now should we add a warning/error when we find conflicts between confs? I
don't know. It seems indeed that it would benefit some (most?) users, since
the use case where someone need different versions for different confs seems
to be rare. But we should be able to disable this behavior.
