- set up a repository manager in ~/.m2/settings.xml that is not yet running
- start continuum
- attempt to add a maven 2 project that has a valid parent
- it will fail, since the parent can't be found
- start the repository manager, such that the parent is found at the right URL
- adding a project will still fail
It appears the resolution result is cached, and should never be for this scenario.
Restarting Continuum resolves the issue.
