[jira] (MNG-4142) Maven doesn't try to download a dependency when it already exists a version with classifier locally

["nodje (JIRA)" <ji...@codehaus.org>]

    [ https://jira.codehaus.org/browse/MNG-4142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=301056#comment-301056 ] 

nodje commented on MNG-4142:
----------------------------

We're a year after the latest comment, could someone update the Fix version, that'd give some hope.

Our team is severely being affected by this problem, and it seems to be larger than the description suggests.
We have SNAPSHOT update problem on a daily basis, even for deps than haven't been installed locally. 
A CI server deploy the artifact, and in some case no one seem to get the updated artifact.

Thanks for pointing me to other bug report if my problem is out of scope here.

> 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.
