Mill is a fast JVM build tool that supports Java and Scala. Mill aims to make your project’s build process performant, maintainable, and flexible.
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:
package build
import mill._, javalib._
object foo extends JavaModule {
def ivyDeps = Agg(
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() ++ Agg(
ivy"com.google.guava:guava:33.3.0-jre"
)
}
}> ./mill foo.compile # compile sources into classfiles
