Description

Resolver (1.9.8-1.9.12) contained a nasty bug, that was triggered in Maven under certain circumstances and is related to file locking.
Example reproducer:

• using file-lock factory and file-gav naming
• the built project has a snapshot dependency
• the snapshot dependency has a snapshot parent
• here, model builder will want to resolve parent POM and cause "lock upgrade"

Reproducer for 3.9.2 bug: https://gist.github.com/cstamas/0f1909c81d975f513ceb88012d7c0529
