Mill is a fast, scalable, multi-language build tool that supports Java, Scala,

Kotlin, and Python:

* Mill builds the same Java project 3-6x faster than Maven

or Gradle due to aggressive caching & parallelism

* Mill has better IDE support than other build tools, with

superior autocomplete and navigation in IntelliJ

* Mill builds require fewer plugins for common workflows,

and are easier to extend with custom tasks

If you want to use Mill in your own projects, check out our documentation:

* {link-current-doc-site}[Documentation]

Here is some quick example, so that you can imagine how it looks:

[source,scala,subs="verbatim,attributes"]

----

package build

import mill._, javalib._

object foo extends JavaModule {

  def ivyDeps = Seq(

    ivy"net.sourceforge.argparse4j:argparse4j:0.9.0",

    ivy"org.thymeleaf:thymeleaf:3.1.1.RELEASE"

  )

  object test extends JavaTests with TestModule.Junit4 {

    def ivyDeps = super.ivyDeps() ++ Seq(

      ivy"com.google.guava:guava:33.3.0-jre"

    )

  }

}

----

[source,bash]
