Mill is a fast build tool for Java, Scala, Kotlin and other JVM-based projects. It is designed as a simpler and more efficient alternative to established tools such as Maven, Gradle and sbt.
The software supports concise declarative builds using build.mill.yaml files as well as programmable object-oriented build definitions for more complex projects. It can manage compilation, external dependencies, tests, executable applications, packages and software publishing.
Mill models build operations as tasks with explicit dependencies. It uses aggressive caching and parallel execution to avoid unnecessary work and reduce build times, while supporting projects ranging from small applications to large multi-module repositories.
This is free and open source software.
Key Features
- Builds projects written in Java, Scala, Kotlin and other JVM languages.
- Supports concise declarative build.mill.yaml files.
- Offers programmable object-oriented build definitions.
- Caches completed tasks to avoid repeating unchanged work.
- Runs independent build tasks in parallel.
- Supports incremental compilation.
- Manages external libraries and transitive dependencies.
- Handles multi-module projects and monorepositories.
- Runs applications and automated test suites.
- Creates distributable packages and assembly JAR files.
- Supports publishing packages to software repositories.
- Extensible through built-in and third-party plugins.
