Snapshots resolution issue

[Julien CARSIQUE <jc...@nuxeo.com>]

Hello,

I have an issue with Nexus that seems to be linked to Maven.

Getting a snapshot from a Nexus group including two repositories doesn't 
give me the latest one.
Here's the metadata, I'm waiting for the latest artifact (from internal 
repository) which is 5.2.1-20091006.153450-66 but I get an older one 
(from public repository) 5.2.1-20090925.015004-82.
It appears to be because of the buildnumber which is inevitably 
inconsistent because those artifacts may come from two different 
repositories.

    <?xml version="1.0" encoding="UTF-8"?>
    <metadata>
      <groupId>org.nuxeo</groupId>
      <artifactId>nuxeo-ecm</artifactId>
      <version>5.2.1-SNAPSHOT</version>
      <versioning>
        <snapshot>
          <timestamp>20090925.015004</timestamp>
          <buildNumber>*82*</buildNumber>
        </snapshot>
        <lastUpdated>20091006153451</lastUpdated>
      </versioning>
    </metadata>

Bad: nuxeo-ecm-5.2.1-20090925.015004-*82*.pom
Good: nuxeo-ecm-5.2.1-20091006.153450-*66*.pom

Here's an answer I get from Nexus mailing list:
<< this seems like a Maven issue. Nexus uses the Maven Artifact stuff 
(version 2.2.1 currently), and this is from there:
http://svn.apache.org/viewvc/maven/maven-2/branches/maven-2.2.x/maven-artifact/src/main/java/org/apache/maven/artifact/versioning/DefaultArtifactVersion.java?view=markup
It seems that only build number is compared at all. This would explain 
why maven and also nexus behaves the same wrong way. >>

This wrong behavior breaks the continuous integration infrastructure 
I've setup and I don't see how to workaround this.

Thanks for help,

Hello,

I'm raising back that issue, still present with Maven 3.
http://jira.codehaus.org/browse/MNG-5008

The issue is blocker for us, since Jenkins relies on Maven API and Nuxeo's
continous integration build chain is using three separate Maven
repositories, and our deployment policy depending on the QA status of the
artifacts.

Thanks,

The fix was to override the maven behavior, so I think in some cases
Maven can still get the wrong snapshot if it's present in multiple
repos.

Forget it, there's a fix in Nexus 1.4 about this (NEXUS-2472), maybe not 
a Maven bug :)

Thanks
