Resolution: Duplicate
> Initialization of Extensions like Wagon happens after Retrieval of Parent-POM
> -----------------------------------------------------------------------------
>
> Key: MNG-3253
> URL: http://jira.codehaus.org/browse/MNG-3253
> Project: Maven 2
> Issue Type: Bug
> Components: Artifacts and Repositories
> Affects Versions: 2.0.7
> Reporter: Benjamin Bentmann
> Assignee: Brett Porter
>
> Consider the following scenario:
> Artifacts are stored in an organization-specific repository using some
> protocol like sftp, scp or ftp. To properly access this repository, one needs
> to enable the proper wagon using a build <extension>. No troubles so far. Now
> project "dummy" inherits configuration from project "parent". The
> corresponding Parent-POM needs not to be located in the local file system of
> the executing user (e.g not checked out from scm) but should be retrieved
> from the repository like any other artifact. Unfortunately, Maven initializes
> build extensions like wagon after the artifact resolution for the Parent-POM.
> So, when the Parent-POM needs to be retrieved from a repository and this
> repository requires a specific wagon but this wagon has not been initialized
> yet, the build will fail:{code}
> [INFO] Scanning for projects...
> [DEBUG] Searching for parent-POM: de.test:parent::SNAPSHOT of project:
> null:dummy:jar:null in relative path: ../pom.xml
> [DEBUG] Parent-POM: de.test:parent::SNAPSHOT not found in relative path:
> ../pom.xml
> [DEBUG] Retrieving parent-POM: de.test:parent::SNAPSHOT for project:
> null:dummy:jar:null from the repository.
> [INFO] snapshot de.test:parent:SNAPSHOT: checking for updates from
> some-ftp-repo
> [WARNING] repository metadata for: 'snapshot de.test:parent:SNAPSHOT' could
> not be retrieved from repository: some-ftp-repo due to an error: Unsupported
> Protocol: 'ftp': Cannot find wagon which supports the requested protocol: ftp
> ...
> [ERROR] FATAL ERROR
> [INFO]
> ------------------------------------------------------------------------
> [INFO] Failed to resolve artifact.
> {code}
> Initializing build extensions from the current project, at least core stuff
> like wagon, should be the first build task such that repository access is
> always possible.
