Roy Lyons commented on MNG-4537:
--------------------------------
:) personally I like this feature. I didn't think it was a bug. This way when
my developers have a failure to download a dependency because they had to
update JAVA *yet again* because of the ongoing quarterly critical security
patches from Oracle -- I can simply tell them to add a -U on their next run to
expire the failure cache in their .m2
> --update-snapshots command line option flag is misleading, as it actually
> updates releases too

> Had a discussion with Brett Porter, Brian Fox, and Benjamin Bentmann on IRC
> about how the --update-snapshots command line option is misleading. I, as
> well as some of my students, we using -up, expecting downloads that
> previously failed to be tried again. However, that flag only checks for
> metadata updates to see if a newer version of the plugin has been released.
> What we were after is the -U flag (synonymous with --update-snapshots) which
> also checks again remotely for SNAPSHOT and RELEASE downloads that previously
> failed.
> Brett and Brian suggested that we either deprecate the old --update-snapshots
> long option, but that's not entirely possible since the short and long
> options are tied together. So, as a compromise solution, I'm indicating that
> the --update-snapshots option flag (name) may go away in the future and
> adding a migrate-to option called --update-all which was suggested in the
> above IRC conversation. Functionally, this long flag performs the same
> operation as --update-snapshots, but the name much more effectively
> communicates that it updates all artifacts from remote repos, not just
> snapshots.
