7.3.1 Error: No such option: --verbosity (Possible options: --verbose, --version)

[Anatoli Babenia]

Snapcraft help shows verbosity option

    $ snapcraft -h
    ...
                      --verbosity: Set the verbosity level to 'quiet',
                                    'brief', 'verbose', 'debug' or
                                    'trace'

The option works but fails when legacy implementation is run. To reproduce, run the `snapcraft --verbosity trace` on snaps that are not core-22.

This is the line that produces the message https://github.com/snapcore/snapcraft/blob/d8d4ce07716f72f10c67006ee47339893ebf983e/snapcraft/legacy_cli.py#L44
It looks like the arguments are not explicitly passed to legacy CLI, and `click` in legacy uses the same global `sys.argv`, which contains newer options.

The solution could be to whitelist only supported options and transform `--verbosity trace|debug` into `enable_developer_debug` option for legacy code.

Hi Anatoli!

Thanks for reporting this bug. I can confirm that the `--verbosity` argument is not supported for building core18|20 snaps. I appreciate the suggestions too.

[Aritra Basu (nevgen)]

@mr-cal is this being worked on or is it something I can take up?

[Callahan Kovacs (mr-cal)]

Hi @nevgen!

Thanks for reaching out. This may not be a good issue to take on, because we're planning to solve this as part of a larger effort described here: https://github.com/snapcore/snapcraft/issues/4194

[Aritra Basu (nevgen)]

Ah, that's fair. Thanks for letting me know
