Worked on the typelevel/sbt-typelevel repository to enhance compatibility and maintainability for Scala projects targeting modern Java versions. Implemented Java 17 output version support for Scala 3.8 and above, ensuring smoother integration with the latest Java features. Refactored the Java output version matching logic using Scala and SBT, making the configuration process clearer and reducing the risk of misconfiguration across Scala versions 3.2 through 3.8. This work improved the maintainability of the plugin and aligned it with evolving Java requirements, enabling downstream projects to adopt new Java features more efficiently while maintaining robust version handling and plugin development practices.
