• Works with any branch (main, develop, feature branches)
• No hard-coded branch names

✅ Maven pom.xml versioning automatically managed

• Maven release plugin handles all version updates
• Two commits created: release version + next SNAPSHOT
• All submodules updated together with autoVersionSubmodules
• Simplified: Maven calculates next version automatically

✅ Release artifacts deployed automatically

• Deployment to Maven Central with GPG signing
• Includes: compiled JARs, sources, javadocs
• Only production modules deployed (excludes samples)

✅ All manual steps eliminated

• No manual Maven commands needed

📦 Changes Summary

1. Updated Workflow .github/workflows/release.yml (138 lines)

Complete automation using Maven release plugin with 9 steps:

1. Validate release tag format (vX.Y.Z)
2. Auto-detect target branch from target_commitish
3. Checkout repository at target branch
4. Delete user-created tag (recreated by Maven)
5. Set up JDK 17 with Maven cache
6. Configure git user for commits
7. Run release:prepare with release version (Maven calculates next version)
8. Run release:perform to build and deploy
9. Push commits and tag to originating branch

Key Features:

• Tag validation with clear error messages
• Branch auto-detection (no hardcoded main)
• Standard Maven release plugin workflow
• Maven automatic version calculation (simplified)
• Comprehensive error handling
• Proper git tag management
• Clean configuration (removed redundant Maven server setup)
• Git-only parameters (removed SVN-specific options)

Simplifications:

• Removed manual next version calculation (Maven handles it)
• Removed cleanup step (unnecessary in ephemeral runner)
• Removed redundant Maven server configuration from setup-java
• Removed SVN-specific -DremoteTagging parameter

2. Updated .github/workflows/maven-publish.yml

• Added deprecation notice
• Renamed to "Maven Release (Manual - Deprecated)"
• Kept for backward compatibility

3. Updated Documentation RELEASING.md (streamlined)

Focused documentation covering:

• Quick start overview
• Step-by-step release instructions with target branch selection
• Updated workflow diagram showing Maven release plugin flow
• Detailed troubleshooting guide (simplified)
• Updated branch strategy (no separate release branches)

Removed unnecessary sections:

• Re-releasing section (covered in main troubleshooting)
• Permission denied entry (already covered)
• Local branch already exists (not applicable)

4. Updated README.md

• Added Contributing section
• Links to RELEASING.md

🔄 How It Works

User Action (1 step)

Create GitHub Release → Tag: vX.Y.Z → Target: main (or any branch) → Publish

Automated Workflow (9 steps, ~5-10 minutes)

1. Validate tag format
2. Auto-detect target branch (from target_commitish)
3. Checkout target branch
4. Delete user-created tag
5. Run Maven release:prepare
   - Commit 1: Update pom.xml → X.Y.Z (release)
   - Create tag vX.Y.Z → Commit 1
   - Commit 2: Update pom.xml → Maven-calculated next SNAPSHOT
6. Run Maven release:perform
   - Checkout tag vX.Y.Z
   - Build, test, and deploy to Maven Central
7. Push commits 1 & 2 to originating branch
8. Push tag vX.Y.Z

Result

✅ Release artifacts on Maven Central
✅ Tag vX.Y.Z → Release commit (version X.Y.Z)
✅ Target branch → Next SNAPSHOT commit (Maven-calculated version)
✅ No separate release branches
✅ Ready for next release

<issue_title>[Chore]: Simplify and Automate Release Workflow</issue_title>
<issue_description>### What

Description

Currently, the release process involves multiple manual steps, including creating a release branch (release-x.x.x), running the Maven release action manually, and then creating a release in the GitHub user interface. Additionally, the Maven release plugin requires pom.xml file modifications to be committed, further complicating the process.

Why

Goals:

• Simplify the release process so it can be triggered entirely via the GitHub release interface.

• Automate the creation of the release-x.x.x branch with the correct semantic versioning numbers.

• Include the Maven release plugin’s goals (release:prepare and release:perform) to manage pom.xml version changes, tagging, and deployment.

Notes

Proposed Approach:

1. Update the GitHub Actions workflow to trigger on the release:created event.

2. Automate the creation of the release-x.x.x branch dynamically based on the release version provided in the GitHub interface.

3. Use the Maven release plugin to:

• Update and commit pom.xml version changes.

• Create and push the release tag and branch.

• Build and deploy the release artifact (e.g., to a Maven repository).

4. Ensure the workflow includes proper permissions to create branches and commit changes.

Acceptance Criteria

• Release workflow triggers entirely from the GitHub interface.

• release-x.x.x branch is dynamically created based on versioning.

• Maven pom.xml versioning changes are automatically managed.

• Release artifacts are deployed automatically.

• All manual steps are eliminated or reduced to a single interaction in the GitHub interface.</issue_description>

@copilot I propose updating the release workflow to use the tag created by the user as the single source of truth for the release version. The release flow would work as follows:

User action: Create a GitHub Release (for example, tag v1.2.0)
 ↓
GitHub: Creates tag v1.2.0 from the user-specified branch (via target_commitish)
 ↓
Workflow: Triggered by the release event
 ↓
Workflow: Run release:prepare using the version extracted from the tag (e.g. 1.2.0)
 ↓
Workflow: Run release:perform to build and deploy artefacts to Maven Central
 ↓
Workflow: Move the tag v1.2.0 so it points to the first commit created by release:prepare (the actual release commit)
 ↓
Workflow: Push the updated tag and the new -SNAPSHOT commit back to the originating branch
 ↓
Result:
• Tag v1.2.0 points to the correct release commit
• The originating branch (typically main) now contains the next -SNAPSHOT version
• Maven Central receives the published artefacts from a consistent, reproducible source commit

Additional improvements
• Branch autodetection:
The workflow can use github.event.release.target_commitish to determine which branch the user created the tag from. This avoids hard-coding main and keeps the workflow flexible.
• Safety check:
Before running the release, the workflow can verify that the tag’s commit exists on the expected branch, preventing accidental releases from feature branches.

@copilot I propose updating the release workflow to use the tag created by the user as the single source of truth for the release version. The release flow would work as follows:

User action: Create ...

Implemented your proposed design! The workflow now:

• Uses the tag from the GitHub release as the single source of truth
• Runs release:prepare with the version extracted from the tag
• Runs release:perform to build and deploy to Maven Central
• Auto-detects the originating branch using github.event.release.target_commitish
• Pushes commits and the updated tag back to the originating branch (no separate release branches)

The tag is moved by Maven's release plugin to point to the actual release commit, and commits are pushed directly to the target branch you selected when creating the release.

Implemented in commit f096dff.
