Can't use repositories in protocols other than http
---------------------------------------------------
Key: MNG-2227
URL: http://jira.codehaus.org/browse/MNG-2227
Project: Maven 2
Type: Bug
Components: Repositories
Versions: 2.0.4
Reporter: Carlos Sanchez
Attachments: log.txt
When adding the wagon-scm to the build extensions to *add* another scm based
repo (not to replace the http one) Maven fails because tries to validate the
scm repo before downloading the wagon-scm jar from the http repo.

[WARNING] repository metadata for: 'snapshot
