> Fix behaviour of the maven update policy
> ----------------------------------------
>
> Key: MNG-7802
> URL: https://issues.apache.org/jira/browse/MNG-7802
> Project: Maven
> Issue Type: Bug
> Reporter: Guillaume Nodet
> Assignee: Guillaume Nodet
> Priority: Major
>
> The update policy can be specified using the {{-U}} (force update) or
> {{-nsu}} (no update) options, but those options change the whole repository
> session policy and override any settings on the repositories.
> This means that if {{-U}} is set, the resolver will attempt to check already
> downloaded artifacts. This is wrong and the behaviour has been inherited
> from maven 2.x.
> What we really wants (and what's implied by the name of the options and docs)
> is to check for new artifacts / updates, so this mainly affect _version
> resolution_ and not {_}artifact resolution{_}.
>
>
> Also, the CLI options for {{-U}} and {{-nsu}} indicates that those are for
> snapshots, while they actually affect all policies, so those should be
> renamed and their doc fixed.
