Publish generator dev versions during RegenPreview so emitter deps are restorable in CI by Copilot · Pull Request #11280 · microsoft/typespec

Copilot · 2026-07-16T19:59:48Z

The regen-preview pipeline rewrites the Azure/mgmt *-emitter-package.json artifacts to point at host-only file: .tgz paths, so CI on the resulting azure-sdk-for-net PR always fails to restore those dependencies (example). This adds an opt-in path to publish the locally built generator packages to the registry configured in .npmrc and reference the published version instead.

Changes

RegenPreview.psm1
- Publish-GeneratorPackage: publishes a .tgz to a registry; treats an already-published version as success so re-runs are idempotent.
- Update-EmitterPackageArtifact: shared helper to rewrite an emitter-package.json + lock file in either file: mode (default) or published-version mode.
- Update-GeneratorPackage gains -PublishRegistry/-NpmrcPath: pins deps to the published version (not file:) and publishes the packed .tgz.
- Update-AzureGenerator / Update-MgmtGenerator thread these through and use the shared helper.
Submit-AzureSdkForNetPr.ps1: new -PublishGeneratorPackages switch that resolves the registry + authenticated .npmrc and drives publishing through the Azure/mgmt regeneration paths.
publish.yml: new opt-in PublishGeneratorPackages pipeline parameter.

With the switch off (default), behavior is unchanged — deps stay pinned via file:. Publishing order (unbranded from the main stage → Azure → mgmt) ensures each package's dependencies are resolvable from the feed; the local RegenPreview.ps1 loop is untouched since it cleans up and never commits.

Result

The emitter artifact references a published version restorable by CI:

// azure-typespec-http-client-csharp-emitter-package.json (published mode)
"dependencies": {
  "@azure-typespec/http-client-csharp": "1.0.0-alpha.20250101.abc"  // was "file:/…/…-*.tgz"
}

Pull request overview

This PR restructures the http-client-csharp publish pipeline’s azure-sdk-for-net regeneration flow to support publishing generator npm packages to an ADO feed and pinning regenerated *-emitter-package.json artifacts to restorable versions (instead of host-only file: paths), so downstream azure-sdk-for-net CI can restore emitter dependencies.

Changes:

Split Submit-AzureSdkForNetPr.ps1 into discrete Prepare / BuildGenerators / Regenerate phases that share a single on-disk azure-sdk-for-net checkout and generator package folder.
Added Get-NextGeneratorVersion + Update-EmitterPackageArtifact helpers in RegenPreview.psm1 to compute next feed versions and rewrite emitter-package artifacts for either local file: or published-version mode.
Centralized npm publishing to the ADO feed via a reusable pipeline step template and updated emitter pipeline stages to use it.

@copilot fix this

Fixed in 5521a55. The BuildGenerators phase now copies the unbranded typespec-http-client-csharp-*.tgz into $DebugFolder and uses that staged path for the downstream Azure/mgmt generator steps.

    $azurePackagePath = Join-Path $DebugFolder $azurePackageName
    $unbrandedPackagePath = Join-Path $DebugFolder $unbrandedPackageName



@copilot fix this

Fixed in 7a791a8. Publish-mode now skips the local Azure/unbranded tgz existence checks, so mgmt regen only validates those staged tgz paths in file-mode.

@copilot fix this. PublishGeneratorPackages should be on when running in CI mode only

Fixed in 7a791a8. Submit-AzureSdkForNetPr.ps1 now has an explicit -PublishGeneratorPackages switch, and publish.yml only passes it from the CI pipeline when Azure or mgmt regeneration is requested, so local regen stays on file: references by default.

jorgerangel-msft · 2026-07-20T22:44:39Z

+    .PARAMETER PublishRegistry
+        When provided, dependencies are pinned to their published versions (see PublishedDependencyVersions)
+        instead of a local "file:" path, and the packed .tgz is published to this registry so the resulting
+        emitter artifacts reference a version that CI can restore.


@copilot fix this

Fixed in 7a791a8. The PublishRegistry docs now describe stamping the package for the pipeline publish flow instead of claiming the helper publishes it directly.

Addressed in 831793c. I pulled latest main, resolved the conflicts in publish.yml and Submit-AzureSdkForNetPr.ps1, and kept the newer Build.Reason handling wired through the shared submit arguments.
