Tamas Cservenak commented on MNG-7803:
--------------------------------------
I'd deprecated the existing ones (emit warning and all that).
{noformat}
-nsu,--no-snapshot-updates Suppress SNAPSHOT updates
-U,--update-snapshots Forces a check for missing
releases and updated snapshots on
remote repositories {noformat}
Thext for -nsu is totally off (should be "Supress ANY updates"), while -U is
kinda conflicting with {{updatesnapshots}} as "forces check for missing
releases"?
Instead, introduce:
* -au "always update" => behave as -U today (in maven, so set session level
policy "always")
* -nu "never update" => behave as -nsu today (in maven, so set session level
policy "never")
* and add a resolver config (new, for example
{{{}aether.updateCheckManager.applyPolicy{}}}) that controls whether is update
policy applied to "all" (artifact and metadata, as today) or "metadata" only
(default to "metadata")
This would mean, that CLI line like {{-au
-Daether.updateCheckManager.applyPolicy=all}} in maven 4 would result as -U is
in Maven3 today.

> The CLI options for {{-U}} and {{-nsu}} indicates that those are for
