[jira] [Commented] (MRESOLVER-224) DefaultVersionResolver is inflicting ArtifactNotFoundException for classifiers with SNAPSHOT version

["Tuomas Kiviaho (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MRESOLVER-224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17445308#comment-17445308 ] 

Tuomas Kiviaho commented on MRESOLVER-224:
------------------------------------------

The problem is that even though metadata's {{<lastUpdated>}} is checked the existence of corresponding {{<snapshotVersion><classifier>}} of {{SNAPSHOT<classifier>:<extension>}} is not assured to exist in the repo that {{SNAPSHOT}} points to.

{code:java|title=DefaultVersionResolver}
                String key = SNAPSHOT + getKey( artifact.getClassifier(), artifact.getExtension() );
                merge( infos, SNAPSHOT, key );
                if ( !resolve( result, infos, key ) )
                {
                    result.setVersion( version );
                }
{code}

>          Issue Type: Bug
>          Components: Resolver

> I use classifier artifact along with the artifact itself as a dependency in a Maven Invoker Plugin project. The project that calls the invoker has the artifact itself as a dependency, but no reference to the classifier.
> This causes resolving of the maven-metadata.xml for the project itself plus downloading of the dependency artifact.When invoker is called the artifact is already downloaded to the local repo and cached with SNAPSHOT key.
> This causes the DefaultVersionResolver to merge the version information of the SNAPSHOT<myclassifier>:jar artifact that is now being resolved with the already downloaded SNAPSHOT key. Since the local version is newer than the repo version the DefaultVersionResolver thinks SNAPSHOT<myclassifier>:jar to be outdated thus overriding it with local repo.
> Since the SNAPSHOT<myclassifier>:jar doesn't exist in the local repo there are no remote report left to try the DefaultArtifactResolver fails ultimately to ArtifactNotFoundException since there was no download task.
> {code:java}
> [INFO] [DEBUG] Resolving artifact <mygroupid>.<myartifactid>:jar:<myclassifier>:<mybaseversion>-SNAPSHOT from []{code}
