Motivation

Releases are drafted from this repo but published to Maven Central from a separate central workflow, which loads the GPG key for the whole Maven build. This moves publishing here and narrows where the signing key is used: merging the release PR publishes to Maven Central and the drafted release once a maintainer approves it.

Changes

• Add a Release workflow that runs when CHANGELOG.md changes on main, with a manual run and a dry run as a fallback
• It runs only when a draft release matches the top CHANGELOG.md version, so ordinary changelog edits are skipped
• mvn verify runs the tests and stages the jar, sources, javadoc and pom into a local repository layout with signing skipped (-Dgpg.skip) and no secrets; the build fails if the pom.xml version doesn't match CHANGELOG.md
• Publishing waits for approval on the release environment, then signs every staged file with gpg (key and passphrase from that environment, in a temporary keyring removed afterwards), so the key never meets the Maven build or its plugins
• The signed bundle is uploaded to the Central Portal and the job waits until Central is publishing it; the jars are attached to the GitHub Release and the draft is pinned to the merged commit before it is published

Before merging

• GPG_PRIVATE_KEY, GPG_PASSPHRASE, MAVEN_CENTRAL_USERNAME and MAVEN_CENTRAL_PASSWORD exist in the release environment

How to test

• Run the Release workflow manually with dry_run checked: detect and build pass, the central-staging artifact holds the pom and three jars with checksums, Publish is skipped
• Merge the next release PR and approve the release deployment: Central accepts the bundle, the version appears on Maven Central with .asc signatures, and the release has the jars attached and its tag on the merge commit

Summary by CodeRabbit

• Chores
  • Automated release runs verify that the project version matches the changelog and that the build passes before preparing packages.
  • Successful releases publish signed packages to Maven Central and attach JAR files to the corresponding GitHub release.
  • Dry runs check and stage packages without publishing them. Regular changes without a pending release are skipped; manual runs without a pending version fail unless dry-run mode is enabled.
  • Publishing stops if the version is already on Maven Central, the GitHub release is invalid, or Maven Central reports a failure or times out.

Walkthrough

A new GitHub Actions workflow detects pending releases from changelog updates or manual dispatch. It builds and stages Maven artifacts, then publishes them to Maven Central and GitHub Releases unless the run is a dry run.

Changes: Maven release workflow

Layer / File(s)	Summary
Release triggers and detection .github/workflows/release.yml	The workflow runs for changelog updates to main or manual dispatch. It checks the default branch and handles pending releases, including dry-run and no-release cases.
Build and stage artifacts .github/workflows/release.yml	The build job checks the Maven version against the detected release, runs verification, stages artifacts without signing, and uploads the staging directory.
Publish Maven Central and GitHub releases .github/workflows/release.yml	The publish job validates the release, signs and bundles artifacts, uploads the bundle to Maven Central, and polls deployment status. It then attaches JARs to and publishes the GitHub release.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Moderate · previous review f5930

The release workflow may skip a pending release, fail to recover after a partial publish, run unpinned third-party actions with release credentials, or publish the GitHub release before Maven Central finishes. Resolve or explicitly accept these before merging.

Review comments at @.github/workflows/release.yml:
- Line 143: Pin the Railsware actions used by the release job, including
check-sdk-github-release and publish-github-release, to reviewed commit SHAs
instead of the mutable master ref; use verified SHAs for each action.
- Line 209: Update the release-status polling logic around the
PUBLISHING|PUBLISHED case so PUBLISHING continues polling and publishing the
GitHub release proceeds only after PUBLISHED. Preserve the existing FAILED
handling and polling deadline behavior.
- Line 138: Update the version-check flow containing the `200` branch so an
already-published `VERSION` is reconciled rather than treated as a fatal error:
verify that Central contains the expected release artifacts, skip the Central
upload when they are present, and continue the workflow so the draft GitHub
release can be completed. Establish the repository’s existing
artifact-verification mechanism and preserve failure behavior when verification
does not confirm the expected artifacts.
- Line 51: Update the detect job’s use of resolve-pending-release so the
resolver receives a supported token with sufficient access to list draft
releases; establish the action’s token interface and grant only the required
repository access rather than assuming contents: read is sufficient. Verify
detection against an actual draft release.
