Worked on the i-Cell-Mobilsoft-Open-Source/coffee repository to modernize its continuous integration and documentation by establishing Java 17 as the new minimum supported version. The update involved removing Java 11 from all CI workflows and systematically upgrading build configurations to ensure compatibility with Java 17. Leveraging YAML for GitHub Actions and adoc for documentation, the work reduced technical debt and aligned the project with current Java support lifecycles. No major bugs were addressed during this period, with the focus remaining on CI/CD modernization and clear documentation practices to support ongoing development and enable the use of Java 17 features.
