[regression] Outdated remote snapshots are preferred over locally installed
snapshots
-------------------------------------------------------------------------------------
Key: MNG-4955
URL: http://jira.codehaus.org/browse/MNG-4955
Project: Maven 2 & 3
Issue Type: Bug
Components: Artifacts and Repositories, Dependencies
Affects Versions: 3.0.1
Reporter: Benjamin Bentmann
When using the new metadata format, remote snapshots listed by locally cached
{{maven-metadata-*.xml}} will always be selected regardless of their relative
age compared to any locally installed snapshots. To repro:
a) "mvn deploy" lib-a
b) wait a few seconds
c) "mvn install" lib-a, this creates a local snapshot that is newer than the
remote snapshot
d) in a dependent project lib-b, "mvn compile -U"
The -U flag to enforce metadata download is rather crucial as otherwise the
feature introduced for MNG-4326 hides the defect.
Besides the expected download of the remote metadata, Maven erroneously also
downloads/uses the remote snapshots.
