Greptile Overview

Greptile Summary

Updated actions/setup-java from v4 to v5 across all GitHub Actions workflows to ensure compatibility with Node 24, as Node 20 will reach end-of-life in April 2026.

Key Changes:

• .github/workflows/blossom-ci.yml: 1 occurrence updated
• .github/workflows/mvn-verify-check.yml: 8 occurrences updated across multiple jobs

Analysis:

• All instances consistently updated from @v4 to @v5
• No changes to action configurations (distribution, java-version remain the same)
• Java versions used (8, 11, 17) are all supported by setup-java@v5
• PR correctly includes [skip ci] tag to avoid unnecessary CI runs
• Proactive maintenance ahead of Node 20 deprecation (March 2026)

Confidence Score: 5/5

• This PR is safe to merge with no risk - it's a straightforward dependency version bump for future-proofing
• The change is a simple, well-documented version upgrade with no configuration changes. The v4 to v5 upgrade of actions/setup-java is backward compatible and only updates the underlying Node.js runtime from 20 to 24. All Java versions (8, 11, 17) remain supported, and the change is consistent across all 9 occurrences.
