Dependency resolution appears to misbehave if a remote repository uses the id 
"local"
-------------------------------------------------------------------------------------

                 Key: MNG-4418
                 URL: http://jira.codehaus.org/browse/MNG-4418
             Project: Maven 2
          Issue Type: Bug
          Components: Artifacts and Repositories
    Affects Versions: 2.2.1
            Reporter: Benjamin Bentmann
            Priority: Minor


Consider something like
{code:xml}
<mirror>
  <id>local</id>
  <mirrorOf>*</mirrorOf>
  <url>http://localhost/mymirror</url>
</mirror>
{code}
in the settings. Note in particular that the mirror uses the id "local". This 
severely impacts dependency resolution as this repo id is internally used for 
the local repository. In particular the path to the locally stored repo 
metadata uses this id, i.e. {{maven-metadata-local.xml}}, making it impossible 
for Maven to distinguish the real local repo metadata from the remote repo 
called "local".

Possible error scenario:
- user installs local snapshot of a artifact A
- Maven checks remote repo "local" for updates of A, thereby overwriting 
{{maven-metadata-local.xml}} and erasing the information about the local 
snapshot
- Maven downloads snapshot version of A from the remote repo, regardless of its 
age compared to the locally installed snapshot
