Paul Andrews commented on IVY-938:
----------------------------------

The file is being served by hudson directly. The configuration I use is as 
follows:

<ivysettings>
        <settings defaultResolver="chained"/>
        <latest-strategies>
                <latest-time name="time"/>
        </latest-strategies>
        <resolvers>
                <chain name="chained" returnFirst="true">
                        <!-- For getting stuff from the Maven 2 repo on 
gendev-lnx -->
                        <ibiblio
                                name="internal"
                                m2compatible="true"
                                usepoms="false"
                                root="http://gendev-lnx:9090/artifactory/repo"/>
                        <!-- For getting stuff from the hudson repo on 
gendev-lnx -->
                        <url name="hudson_sper" changingMatcher="regexp" 
changingPattern=".*SNAPSHOT.*" checkmodified="true">
                                <artifact 
pattern="http://localhost:9090/hudson/job/SPER/lastSuccessfulBuild/artifact/sper/java/dist/[artifact].[ext]"/>
                        </url>
                </chain>
        </resolvers>
</ivysettings>

The snapshot artifact is not in the "internal" repository, it is in 
"hudson_sper". I have traced the TCP traffic to both repositories and Ivy only 
issues one request: an HTTP HEAD request for the artifact itself. At no time 
does it attempt to retrieve an ivy file. The server returns a modification date 
later than the modification date of any copy of the artifact on my local 
machine - either in the ivy cache or in the location that the artifact is 
copied to by the resolver.

I don't see much point 'publishing' an ivy file to hudson_sper, since Ivy makes 
no attempt to access one anyway.

> Fixed name snapshots are not updated even if they are marked as changing and 
> the publication date is changed in repo

>             Project: Ivy
>          Issue Type: Bug
>          Components: Core, Maven Compatibility
>    Affects Versions: 2.0-RC1
>            Reporter: Jyri Kytömäki
>         Attachments: CacheUpdateTest.zip, CacheUpdateTest2.zip, 
> ivysettings.xml

>
> Snapshot releases with static name like 1.2.3-SNAPSHOT are not updated into 
> the cache.
> Same problem is with ivy and maven remote repos.
> Here ivy example:
> Remote ivy repo contains in ivy xml:
> status="integration" publication="20081010104634"
> Cache contains (.xml):
> status="integration" publication="20081010095107"
> But  ivy_resolve does not update the cache. It prints this with verbose 
> output:
> [ivy-resolve] default: Checking cache for: dependency: 
> org#>module;1.2.3-SNAPSHOT {runtime=[runtime]}
> [ivy-resolve] don't use cache for org#>module;1.2.3-SNAPSHOT: changing=true
> [ivy-resolve] local: Checking cache for: dependency: 
> org#>module;1.2.3-SNAPSHOT{runtime=[runtime]}
> [ivy-resolve] local: module revision found in cache: 
> org#>module;1.2.3-SNAPSHOT
> [ivy-resolve]   found org#>module;1.2.3-SNAPSHOT in remote_ivy
> ...
> [ivy-resolve] :: downloading artifacts ::
> [ivy-resolve]   [NOT REQUIRED] org#>module;1.2.3-SNAPSHOT!module.jar
