Worked on the sbt/sbt-git repository to enhance build configuration and support migration to Scala 3. Focused on upgrading the build environment by aligning the Scala 3 version with sbt-2.0.0-M3, ensuring compatibility with the latest build tooling. Addressed Scala 3 compiler warnings by updating method calls and refining string matching syntax, which improved code quality and reduced build noise. These changes strengthened build stability and prepared the continuous integration pipeline for future Scala 3 features. Utilized skills in Scala, sbt, and build tool configuration to deliver targeted improvements that facilitate smoother feature rollouts and more reliable development workflows.
