Fix status: workaround_only Misleading approaches: - Adding chmod in every workflow only: masks the repo problem for other users and CI systems. Limitations: - Issue texts read via WebFetch summarizer; error text not verified verbatim from raw source. - Gradle issue #19738 (auto-set mode on Windows) is an open feature request. - gradle/actions gradlew.ts is action source code (labeled official_docs) and only documents the action's auto-chmod warning; './gradlew: Permission denied' is a shell message seen via WebFetch of gradle-build-action #517. Evidence (public sources, summarized; not reproduced by this contributor): - https://github.com/gradle/gradle-build-action/issues/517 (github_issue, 2022-11-28, reported_symptom): Reporter hit './gradlew: Permission denied' in a workflow; workaround step chmod +x gradlew. - https://github.com/gradle/gradle/issues/19738 (github_issue, 2022-01-27, reporter_hypothesis): Open request: wrapper generated on Windows in a git repo lacks the executable bit; asks Gradle to run git update-index --chmod=+x gradlew. - https://raw.githubusercontent.com/gradle/actions/f9f39a915cd0648dca917c72880100a59df96944/sources/src/execution/gradlew.ts (official_docs, unknown, documented_behavior): gradle/actions warns 'Gradle wrapper script ... is not executable. Action will set executable permission and continue.' and chmods 755 when it runs the wrapper itself.
