Mill

Mill is a build tool for the Scala programming language, designed to be fast, simple, and composable. It provides a declarative build system that supports incremental compilation, dependency management, and multi-module projects, making it a popular choice for Scala developers seeking an alternative to traditional tools like SBT.

Also known as: Mill Build Tool, Mill Build, Mill Scala, Mill for Scala, Mill Build System

Why learn Mill?

Developers should learn Mill when working on Scala projects that require efficient build processes, especially for large codebases with multiple modules. It is particularly useful for teams seeking a more straightforward and predictable build configuration compared to SBT, and it excels in scenarios where incremental builds and caching are critical for productivity.
