Worked on the jenkinsci/oic-auth-plugin repository to enhance developer experience and build reliability by standardizing the local development environment. Focused on documentation, specifically updating the CONTRIBUTING.md file using Markdown to enforce a minimum Maven version of 3.9.6 or later. This change ensures that all contributors use a compatible build toolchain, reducing onboarding friction and minimizing build failures caused by outdated dependencies. By aligning local development requirements with continuous integration workflows, the update streamlines pull request validation and lays the foundation for smoother future feature development. The work emphasized clear communication and process improvement through precise documentation and toolchain standardization.
