Worked on release version synchronization for both the apache/cloudstack and shapeblue/cloudstack repositories, focusing on build management and version control using Maven and Java. Addressed a bug by aligning all pom.xml files in apache/cloudstack to the 4.20.3.0 release, ensuring consistent packaging and reducing repository drift. Delivered a feature in shapeblue/cloudstack by updating Maven pom.xml versions to 4.20.4.0-SNAPSHOT, supporting reproducible builds and project-wide release alignment. The work emphasized deterministic build processes and improved downstream compatibility. Utilized XML for configuration management, ensuring that deployment pipelines remained stable and that versioning was transparent across both repositories during the release cycle.
