Michael Osipov updated MNG-4142:
--------------------------------
Summary: Maven doesn't try to download SNAPSHOT artifacts, if you've
installed them locally (was: Maven doesn't try to download a dependency when
it already exists a version with classifier locally)

> Key: MNG-4142
> URL: https://issues.apache.org/jira/browse/MNG-4142
> Project: Maven
> Issue Type: Bug
> Components: Dependencies
> Affects Versions: 2.0.9, 2.0.10, 2.1.0
> Environment: Java 5, Windows XP
> Reporter: Arnaud HERITIER
> Priority: Critical
> Fix For: Issues to be reviewed for 3.x
>
> Attachments: MNG-4142.patch, test-metadata-local-clover.zip

>
> When maven installs in the local repository an artifact with a classifier,
> and not the principal artifact, it won't try in a reactor to download the
> principal artifact from the remote repository.
> I created a testcase to reproduce it. It's quite simple. You unzip it and in
> the root directory you launch {code}mvn site{code}
> This build uses clover, thus it installs locally cloverified versions of
> artifacts.
> The build will fail because it doesn't find the SNAPSHOT of the module1 :
> {code}
> [INFO]
> ------------------------------------------------------------------------
> [ERROR] BUILD ERROR
> [INFO]
> ------------------------------------------------------------------------
> [INFO] Failed to resolve artifact.
> Missing:
> ----------
> 1) org.apache.maven.it.test-metadata-local-clover:module1:jar:1.0.0-SNAPSHOT
> Try downloading the file manually from the project website.
> Then, install it using the command:
> mvn install:install-file
> -DgroupId=org.apache.maven.it.test-metadata-local-clover -DartifactId=module1
> -Dversion=1.0.0-SNAPSHOT -Dpackaging=jar -Dfile=/pa
> th/to/file
> Alternatively, if you host your own repository you can deploy the file
> there:
> mvn deploy:deploy-file
> -DgroupId=org.apache.maven.it.test-metadata-local-clover -DartifactId=module1
> -Dversion=1.0.0-SNAPSHOT -Dpackaging=jar -Dfile=/path
> /to/file -Durl=[url] -DrepositoryId=[id]
> Path to dependency:
> 1)
> org.apache.maven.it.test-metadata-local-clover:module2:jar:1.0.0-SNAPSHOT
> 2)
> org.apache.maven.it.test-metadata-local-clover:module1:jar:1.0.0-SNAPSHOT
> ----------
> 1 required artifact is missing.
> for artifact:
> org.apache.maven.it.test-metadata-local-clover:module2:jar:1.0.0-SNAPSHOT
> from the specified remote repositories:
> central (http://maven-proxy.groupe.generali.fr/all),
> remote-repo
> (file://E:\jtb\workspaces\tests\test-metadata-local-clover/remote-repo)
> {code}
> It's anormal because I set a "local" remote repository in the build where it
> should try to download it.
> You can validate that it is working by launching :
> {code}mvn install -f module2/pom.xml{code}
> This bug is really annoying for us. It exists for a long long time now. I
> thought it was due to a problem with metadata sent by archiva, but after
> migrating to nexus the problem always occurs.
> I don't know if the problem is in metadata or in the reactor itself. I think
> it is the second one. There are many issues opened about the reactor and
> classifiers.
> Is there some who can try if it can reproduce the error with my testcase ?
> It should be easy to create a real IT for maven with it if it is necessary.
