## ⚠️ OpenRewrite Plugin Configuration
**Note**: Due to version compatibility issues between OpenRewrite plugin and Spring Boot 3.4.5, the build.gradle OpenRewrite plugin configuration is currently disabled.
**To enable when ready**: Use a compatible OpenRewrite version combination or wait for updated plugin compatibility with Spring Boot 3.4.x.
### Alternative Approaches
1. **Use OpenRewrite CLI**: Execute as standalone command via workflow
2. **Gradle Version Pinning**: Pin compatible versions manually
3. **Manual Monthly Updates**: Use the workflow structure with manual dependency updates
## 🚀 Ready for Production
The monthly update workflow is ready and will:
- Automatically create PRs for manual review
- Run comprehensive safety checks
- Provide detailed update reports
- Support emergency rollbacks
- Notify team via Gitea
### Manual Testing
You can test the workflow by:
1. Pushing changes to test branch
2. Triggering workflow manually via Gitea UI
3. Reviewing generated PR structure
4. Validating safety checks
## 📞 Support
All procedures, templates, and documentation are in place for successful monthly dependency updates with maximum safety and manual oversight.
The configuration prioritizes stability and manual review while automating the repetitive dependency update process.
