Pull Request Overview

Adds support for TypeSpec repository layout v2 and refines error handling in sdk_automation.

• Introduce regex-based detection for data-plane and resource-manager folders under specification/…
• Adjust exit logic in sdk_automation to consistently signal failures for single-package runs
• Maintain existing v1 folder matching as a fallback

Comments suppressed due to low confidence (2)

eng/automation/generate.py:256

• New v2 folder-structure parsing logic has been added but no corresponding tests were included. Adding unit tests for both data-plane and resource-manager matches will help ensure this works as intended.

folder_structure_v2_pattern = r"specification/.*/(data-plane|resource-manager)"

eng/automation/generate.py:139

• The sys.exit(1) call is now unconditional in the exception handler, causing premature exit before writing the output file. It should be indented under the if packages and len(packages) == 1: condition (or the earlier logic) so that multi-package runs still write results.

sys.exit(1)

@XiaofeiCao {service} folder in V2 is only one level. So the regex should be specification/[^/]+/(data-plane|resource-manager)

[XiaofeiCao]

Got it. This is only for TypeSpec, and in v1 we don't have data-plane or resource-manager segment for TypeSpec. I think it should be fine.
