- Changed groupId: com.github.rundeck-plugins → com.rundeck.plugins
- Updated Axion with prefix='' (no 'v' prefix)
- Removed hardcoded version (0.1.24-grails7-upgrade-test)
- Updated nexusPublishing.packageGroup to com.rundeck.plugins
- Added PackageCloud publishing configuration
- Version now managed dynamically from git tags
