Easy Build Plugins With Mill
summary
Mill proves easy to extend: building and publishing Docker and Flyway modules from vanilla Scala code, complete with tasks that return JSON metadata, works and is upstreamed. The demo shows a practical cache buster that forces rebuilds when base images change, uses the OS-Lib to write Dockerfiles, and exposes built image tags for CI. A real repo example reports 769 lines in the main module, illustrating how small, focused plugins actually get built and used.
