-------------------------------------
Github user jaikiran commented on the issue:
https://github.com/apache/ant-ivy/pull/65
These changes don't solve the real issue. The details of this issue are
part of the discussion in ant dev mailing list, where I explained what the real
issue is. I do have a completely different code with tests that's not yet ready
to be merged.
> Incorrect revision of dependencies put in to delivered Ivy files
> ----------------------------------------------------------------
>
> Key: IVY-1485
> URL: https://issues.apache.org/jira/browse/IVY-1485
> Project: Ivy
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.3.0, 2.4.0-RC1
> Reporter: Perrin Morrow
> Assignee: jaikiran pai
> Priority: Critical
> Attachments: 0001-Add-test-cases-for-IVY-1485.patch,

> Ivy deliver incorrectly replaces top-level dependency revision with one from
> a transitive dependency in a different conf.
> When writing the resolved Ivy properties into the cache, the Ivy
> ResolveEngine does not take into account the top-level confs. If it finds the
> same dependency on any transitive path it will prefer the resolved revision
> of the transitive dependency over that of the top-level dependency even when
> that transitive dependency is being resolved into a completely different
> top-level conf. This results in a delivered Ivy file, that when resolved
> again will pull in the wrong version of that top-level dependency.
> Consider the following Ivy dependency chain:
> {noformat}
> top-level
> [conf1]
> - modA#1
> [conf2]
> - modB#1
> - modA#2
> {noformat}
> Ivy resolve and retrieve will pull modA#1 into conf1 and modA#2 into conf2,
> as expected.
> Ivy deliver, however, will replace modA#1 with modA#2 in the delivered ivy
> descriptor. When that delivered ivy file is resolved again (by some other
> module depending on it) it will pull in modA#2 into both conf1 and conf2.
> This appears to be a regression in Ivy 2.3.0. It did not happen with Ivy
> 2.2.0. (Maybe related to IVY-1300?)
> We have written some test cases that demonstrate the problem (a diff against
> the Git repository master) which I will attach.
> We're also working on a patch to fix this but so far it has proved elusive.
