Pull Request Check List

Resolves: #10760

• Added tests for changed code.
• Updated documentation for changed code.

Summary

• Respect --no-interaction in poetry publish --build when dist/ already contains artifacts.
• In non-interactive mode, skip the confirmation prompt and proceed with the build/publish flow.
• Keep interactive behavior unchanged (still asks before rebuilding existing artifacts).

Testing

• poetry run pytest tests/console/commands/test_publish.py -q
  • Added coverage for pre-existing dist/ artifacts under non-interactive execution.
  • Existing prompt behavior remains covered for interactive mode.

Summary by Sourcery

Tests:

• Add regression test ensuring poetry publish --build --no-interaction skips the confirmation prompt and still performs the build/publish flow when artifacts already exist in dist/.

Reviewer's Guide

Adjusts the publish command to respect non-interactive mode when build artifacts already exist, and adds a regression test ensuring the confirmation prompt is skipped while the build/publish flow still runs.

File-Level Changes

Change	Details	Files
Gate the existing rebuild confirmation prompt behind an interactivity check so non-interactive runs skip the prompt and proceed.	Wrap the existing publisher.files confirmation logic in an io.is_interactive() check. Preserve the existing confirmation and abort behavior for interactive sessions when artifacts already exist in dist/. Ensure non-interactive runs with --build no longer attempt to prompt and thus proceed with build/publish flow.	src/poetry/console/commands/publish.py
Add a test that verifies publish --build --no-interaction skips the confirmation prompt when artifacts already exist and still triggers build and publish.	Patch Publisher.files to simulate pre-existing artifacts in dist/. Mock PublishCommand.confirm, PublishCommand.call, and Publisher.publish to assert behavior in non-interactive mode. Execute publish --build --no-interaction --dry-run and assert exit code, that confirm is never called, build is invoked once with the expected args, and publish is called once.	tests/console/commands/test_publish.py

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#10760	Ensure poetry publish with --no-interaction does not prompt for confirmation when build artifacts already exist in dist/, so that CI/non-interactive environments are not blocked.	✅
#10760	In non-interactive mode with --no-interaction, automatically proceed with the build/publish flow (equivalent to answering 'yes' to the prompt) even when dist/ already contains artifacts, while preserving the existing interactive behavior.	✅

Possibly linked issues

• poetry publish --no-interaction still prompts when build artifacts exist in dist/, blocking CI pipelines #10760: PR changes publish command to skip confirmation in non-interactive mode with existing dist/ artifacts, fixing the CI-blocking issue.

**suggestion (testing):** Also assert that the confirmation prompt text is not present in the command output

To better cover the user-facing behavior, please also assert that the confirmation prompt text (e.g. "Build anyway?") does not appear in stdout/stderr when running with `--no-interaction`, by capturing the `app_tester` output as done in other tests.

[SergioChan]

Addressed in 8614fbc.

• Extended test_publish_build_no_interaction_skips_confirmation to capture command output/error.
• Added assertions that prompt text ("Build anyway?") does not appear in either stream under --no-interaction.

Targeted validation:

• poetry run pytest tests/console/commands/test_publish.py -k "test_publish_build_no_interaction_skips_confirmation"
