Worked on the salesforce/rules_spring repository to enhance the Spring Boot Bazel rule by introducing new parameters for compatibility management and restriction control. Focused on build system configuration using Bazel and Starlark, the developer implemented restricted_to and target_compatible_with parameters, which are now propagated to subrules for consistent rule graph behavior. This technical approach enables more granular control over build compatibility, reducing misconfigurations and supporting smoother upgrade paths for Spring Boot applications. The work centered on feature development rather than bug fixes, resulting in improved flexibility, maintainability, and reliability for teams building with Bazel in complex environments.
