Worked on the com-lihaoyi/mill repository to deliver per-module JVM version configuration, enabling each module to specify its own Java version for compile, test, and run phases. Leveraged Java and Scala to integrate Coursier-based fetching and usage of custom JVMs, allowing flexible and isolated JVM management across modules. Updated internal worker logic and examples to support this granular configuration, reducing cross-module JVM friction and minimizing build failures related to version mismatches. This approach facilitated smoother upgrades to newer Java versions while maintaining compatibility for legacy modules, demonstrating depth in build tool development, dependency management, and JVM internals within a cross-platform context.
November 2024: Delivered per-module JVM version configuration with Coursier-based custom JVMs in Mill. This enables per-module Java versions for compile, test, and run, and supports fetching/using custom JVMs via Coursier. Changes include updates to examples and internal worker logic to support flexible JVMs, reducing cross-module JVM friction and enabling faster adoption of newer Java versions while maintaining compatibility for legacy modules.
