Underscores in app names not reported properly
Metadata
Current evaluation
The misleading invalid-app diagnostic was addressed by PR #1615 (baef97109); this report remains open but appears obsolete because clearer schema errors replaced the cryptic message.
Suggested action: close resolved
Reason: The report provides a precise two-app reproducer using one and two_three. Launchpad #1606890 records that merged PR #1615, commit baef97109, fixed the same inscrutable underscore-related app-name error by improving invalid app, hook, and part schema errors; the obsolete diagnostic is also absent from current code.

Issue body
If you have a snap with multiple apps, and one of the apps has an underscore in its name (p.s. it'd be nice to see something move on #1616507 :), then a confusing error is reported against the first app only, even if that is valid.
For example, with the attached snapcraft.yaml including an app "one" and "two_three", the error is:
Issues while validating snapcraft.yaml: The 'apps' property does not match the required schema: 'one' is not a valid app name. App names consist of upper- and lower-case alphanumeric characters and hyphens. They cannot start or end with a hyphen.

needs triage | Snapcraft reports the wrong app name in validation errors when an app name contains an underscore: with apps 'one' and 'two_three', the error blames the valid app 'one' instead of 'two_three'. Open since 2014, no labels, comments, or maintainer activity. | |
