Dec 1, 2025

December 2025: Implemented targeted build-system and CI/CD improvements to reduce duplication, streamline pipelines, and boost reliability across two core repositories. Key features delivered include: (1) Plugin Management Build System Enhancement in apache/incubator-kie-kogito-runtimes, which deduplicated plugin declarations, corrected the POM hierarchy, moved pluginMgmt under the proper parent, and aligned Spring Boot version. (2) CI/Build pipeline simplification and dependency cleanup in kiegroup/kogito-pipelines, which removed kie-jpmml from dependencies, eliminated extraneous Bash steps in CI, and updated PR checks to enforce module removals. Major bugs fixed include removal of duplicated dependencies and incorrect build element formatting, along with the corrected Spring Boot version after review. Overall impact: faster, more reliable builds, reduced maintenance burden, and clearer build configuration enabling smoother feature delivery. Technologies/skills demonstrated: Maven/POM refactoring, build-system architecture, CI/CD optimization, dependency management, and cross-repo collaboration.
