Mill is a build tool that improves upon the tools traditionally used in the JVM ecosystem:
https://mill-build.org/mill/comparisons/maven.html[xref:comparisons/maven.adoc][Simpler than Maven],
with declarative build.mill.yaml files often 1/10th the lines of a pom.xml
https://mill-build.org/mill/comparisons/gradle.html[xref:comparisons/gradle.adoc][Easier than Gradle], with object-oriented programmable builds Java developers can intuitively understand
https://mill-build.org/mill/comparisons/performance.html[xref:comparisons/performance.adoc][Fastest builds on the JVM], 3-7x faster than Maven or Gradle due to aggressive caching & parallelism
Although the Java compiler is very fast and the Java language is easy to learn, JVM build tools have a reputation for being sluggish, complicated, and confusing. Mill tries to offer a better alternative that gives the Java platform the developer experience it deserves.
If you want to use Mill in your own projects, check out our documentation:
Here is some quick example, so that you can imagine how it looks:
extends: JavaModule mvnDeps:
./mill compile # compile sources into classfiles ... compiling 1 Java source to...
./mill run --text hello
./mill test ... Test foo.FooTest.testEscaping finished, ... Test foo.FooTest.testSimple finished, ... Test run foo.FooTest finished: 0 failed, 0 ignored, 2 total, ...
