Looks good, but:
* the CLI `-U` should be changed (not snapshot update but all update, I mean
change the help text)
* as IT failures show, IF `-U` present, do what happened before (stick
ALWAYS to session), if not present, do partially what in PR
> Fix behaviour of the maven update policy

> Key: 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{_}.
