Allow non-interactive app selection in init via --appId

[Alexandre Zollinger Chohfi (azchohfi)]

Why

msstore init is the only command that produces the artifacts a PWA publish needs: it calls the PWABuilder API to build the MSIX bundle (*_PWABuilderExtractedBundle) and writes pwaAppInfo.json. That makes it mandatory for the PWA publishing flow, since msstore publish <url> --appId <id> on its own fails while loading pwaAppInfo.json.

But init always showed an interactive app-selection prompt, and there was no way to supply the Store Id up front. On a headless runner that prompt throws:

Cannot show selection prompt since the current terminal isn't interactive.

Net result: a PWA could not be published to the Microsoft Store from GitHub Actions or Azure DevOps at all, even though the Store Id is already known because it was reserved in Partner Center.

Approach

Three changes, all contained in InitCommand:

• New --appId / -id option. When supplied, the app is resolved with GetApplicationAsync and SelectAppAsync is skipped entirely. Named to match the --appId/-id option publish already has, rather than the --app-id spelling suggested in the issue, so it stays consistent with the rest of the CLI's camelCase options.

• Auto-select when the account has exactly one app, but only when running non-interactively. Interactive runs keep prompting so behavior there is unchanged.

• Fail fast with an actionable message when running non-interactively with more than one app and no --appId, instead of letting Spectre throw its generic error:

  Could not select an application because the current environment is not interactive.
  Use the '--appId' option to specify which application should be used, for example: 'msstore init <pathOrUrl> --appId 9PXXXXXXXXXX'.
  You can list the applications registered in your account with 'msstore apps list'.
  

The issue's repro now works end to end:

msstore init "https://my.pwa.example" --publish --publisherDisplayName "My Publisher" --appId 9PXXXXXXXXXX

Notes for reviewers

Non-interactive detection reuses IEnvironmentInformationService.IsRunningOnCI (CI=true for GitHub Actions, TF_BUILD=true for Azure DevOps) rather than IAnsiConsole.Profile.Capabilities.Interactive. This is deliberate: it is already the established "don't prompt" signal in this codebase, used the same way in FulfillApplicationAsync to default the category and listings on CI. It is also the only workable option for tests, since every console in BaseCommandLineTest is created with InteractionSupport.No, so keying off the console capability would have silently broken every existing prompt-based test.

As a secondary safety net, the prompt call is guarded against NotSupportedException so a non-TTY that is not flagged as CI gets the same actionable message. Spectre raises that exception for both non-interactive and non-ANSI terminals, and CreateNewAppAsync (which throws NotImplementedException) sits outside the try, so nothing unrelated is swallowed.

One behavior change worth a look: on CI with more than one app, init now fails fast instead of prompting. That is what previously crashed anyway, so it is strictly an improvement, but it does mean an interactive shell with CI=true set will no longer prompt. This matches the existing contract that IsRunningOnCI means "do not prompt".

ProjectConfiguratorParsesPWASuccessfullyIfOnCIIfPublish was updated to pass --appId, reflecting the new requirement that CI runs identify the app.

Out of scope

Making publish <url> --appId <id> work standalone without a prior init is a much larger change, since PWA packaging lives in PWAProjectConfigurator.ConfigureAsync, which is what calls PWABuilder and writes pwaAppInfo.json. The issue's own proposed fix is the init option, so publish remains init-dependent here.

--publisherDisplayName is not a CI blocker and is left alone; it already has non-interactive escape hatches via the flag itself and msstore settings setpdn.

Testing

Five new tests plus one updated:

• init with an unknown --appId returns -1 with the "Could not retrieve your application" message, and never falls back to listing apps.
• CI with multiple apps and no --appId returns -1 with a message mentioning --appId.
• PWA end to end on CI with -id publishes successfully with no prompt (the exact scenario from the issue, and it covers the short alias).
• CI with a single app auto-selects it and still commits the submission.

Release build (warnings as errors): 0 warnings, 0 errors. Targeted tests: 24/24 passing on both net10.0 and net10.0-windows10.0.17763.0. Two pre-existing PublishCommandUnitTests arm64 failures were confirmed unrelated by re-running them on a clean tree.

Fixes: #146

• GetApplicationAsync observes ct, so Ctrl+C can throw OperationCanceledException here. The broad catch converts that cancellation into an “incorrect AppId” failure (and logs it as an API error) instead of allowing command cancellation to propagate. Rethrow caller-requested cancellation before handling retrieval failures.

                    catch (Exception err)
                    {
                        ctx.ErrorStatus(_ansiConsole, "Could not retrieve your application. Please make sure you have the correct AppId.");
                        _logger.LogError(err, "Could not find application with id '{AppId}'.", appId);
                        return null;
                    }
