release

name: release description: Use when cutting a new release of the jdwp-debugging plugin — bumping the user-facing version, writing a CHANGELOG entry, committing, tagging, and pushing. Triggers — "do a release", "ship X.Y.Z", "release the last commits", "bump the version", "tag a release".

Plugin Release

End-to-end workflow for releasing the jdwp-debugging plugin from this repo.

Never push, force-push, tag-delete-on-remote, or merge without explicit user permission. Local commits and local tags are reversible; remote pushes are not.

What gets released (vs not)

The plugin version (in marketplace.json) is decoupled from the Maven version. Don't try to keep them in sync.

Pre-flight checks

Run all of these before touching anything.

1. Identify the last release. git for-each-ref --sort=-taggerdate --format='%(refname:short) %(taggerdate:short) %(subject)' refs/tags/ | head -5. The most recent vX.Y.Z tag is the baseline. Sanity-check: the latest [X.Y.Z] entry at the top of CHANGELOG.md must equal the version in .claude-plugin/marketplace.json and equal the most recent tag. If any of those three disagree, fix that drift before bumping. (We hit this in 2.2.0 — v2.1.2 tag was missing and had to be back-filled.)

2. Enumerate unreleased commits. git log <last-tag>..HEAD --oneline --no-merges. Read the full bodies for anything ambiguous — the feature/fix/breaking signal lives in the commit body, not the subject.

3. Pick the SemVer bump from the commit set:

   • Any feat: (new MCP tool, new behavior) → minor (X.Y+1.0).
   • Only fix: / chore: / docs: / review: → patch (X.Y.Z+1).
   • Any breaking change (removed/renamed MCP tool, changed default that breaks user scripts) → major (X+1.0.0).
   • When in doubt between minor and patch, ask the user. The release plays out in public — over-bumping is fine, under-bumping is awkward.

4. Check branch topology. git log --all --decorate --oneline --graph -10. The release commit must land on main. Three possible starting states:

   • On main with clean unreleased commits ahead → simplest case, commit there.
   • On a feature branch that's NOT yet merged → commit on the branch, PR will carry the release in. Bump before merging so the PR review sees the version change.
   • On a feature branch that's ALREADY merged via PR → you're on an orphan tip. Cherry-pick onto main (see "Cherry-pick recovery" below). This is the trap we hit in 2.2.0.

5. Confirm the working tree. git status --short. Untracked junk like FIX_*.md, core/, .factorypath, IDE files must stay out of the release commit. Stage explicitly (git add <file> <file>), never git add -A / git add ..

Procedure

1. Bump .claude-plugin/marketplace.json

Two "version" strings to change — top-level marketplace version AND the inner plugins[0].version. Both must move to the new X.Y.Z together.

2. Write the CHANGELOG.md entry

New section at the top, above the previous version. Format is Keep a Changelog, already established in the file:

## [X.Y.Z] — YYYY-MM-DD

### New — <one-line headline>

<2-4 sentence paragraph explaining the motivation, what was broken or
missing before, and what the change does. User-perspective, not
implementation-perspective.>

- **Bold lead-in** — body sentence explaining one bullet.
- **Another bullet** — …

### Fixed — <one-line headline>

<…>

Section headings to choose from (use the ones that fit): ### New, ### Fixed, ### Breaking, ### Output token savings, ### Docs. Mirror the past entries ([2.1.0], [2.2.0]) for tone — paragraphs first, bulleted detail second. Resolve any #N GitHub issue references in the text (resolves #4) — they're useful for cross-linking.

Date: today's date in YYYY-MM-DD. The em-dash separator — is part of the convention.

3. The release commit

git add .claude-plugin/marketplace.json CHANGELOG.md
git commit -m "chore: release X.Y.Z — <short headline>"

Use a HEREDOC for the body. Three paragraphs is the established length (see 7b95e87, 1c40a71):

1. Headline feature, what it does, resolves which issue.
2. Concurrency / behavior fixes that ship alongside.
3. Review polish summary.

Stage only those two files. Never include untracked files or unrelated edits.

4. Annotated tag

git tag -a vX.Y.Z -m "vX.Y.Z — <same short headline as commit>"

All past release tags are annotated (not lightweight) — keep it that way. Subject convention: vX.Y.Z — short description, em-dash separator. Verify with git for-each-ref --format='%(refname:short) %(objecttype) %(subject)' refs/tags/vX.Y.Z — objecttype must read tag, not commit.

5. Push (requires explicit user permission)

git push origin main
git push origin vX.Y.Z

Confirm with the user before each push. Never --force to main.

Cherry-pick recovery (when the release commit is orphaned)

If you bumped the version on a feature branch and the PR was already merged into main before you committed, the release commit sits on an orphan tip. Recovery:

git checkout main
git merge --ff-only origin/main          # catch local main up
git cherry-pick <release-commit-sha>     # replays onto main, new SHA
git tag -d vX.Y.Z                        # if the tag was made on the orphan
git tag -a vX.Y.Z <new-sha> -m "vX.Y.Z — …"

The cherry-pick produces a new SHA. The old tag (if any) still points at the orphan commit — recreate it at the new SHA before pushing. Don't push the orphan; let the feature branch die naturally.

Back-filling a missing tag

A past release commit without a tag (we found v2.1.2 was never tagged):

git tag -a vX.Y.Z <release-commit-sha> -m "vX.Y.Z — <copy headline from commit>"
git push origin vX.Y.Z

Tag the release commit itself (the one with chore: release X.Y.Z in the subject), not the merge that pulled it in.

Red flags

• marketplace.json and CHANGELOG.md show different versions after your edits → you forgot one of the two version strings in JSON, or skipped the changelog.
• git log <last-tag>..HEAD lists merge commits but no feature commits → you're tagging from the wrong baseline; find the actual last release commit.
• The release commit's parent is not the current origin/main tip → either rebase or cherry-pick before pushing.
• git for-each-ref refs/tags/vX.Y.Z shows objecttype commit not tag → lightweight tag by accident, redo with -a.
• Working tree has untracked files when you stage → audit them; git add -A will swallow them.

Verification after push

git fetch origin
git log HEAD..origin/main --oneline      # should be empty
git log origin/main..HEAD --oneline      # should be empty
git ls-remote --tags origin | grep vX.Y.Z   # tag exists on remote
