Quickstart

Mill version 0.10.0 or newer is required.

import $ivy.`de.tototec::de.tobiasroeser.mill.spring.boot::0.0.1`

import mill._
import mill.scalalib._
import de.tobiasroeser.mill.spring.boot.SpringBootModule

object app extends JavaModule with SpringBootModule {
  override def springBootToolsVersion = "2.7.14"
}

# Run the Spring-Boot Application
$ mill app.run

# Package as executable Spring-Boot Application
$ mill app.springBootAssembly

Targets and Configuration

Your module needs to extend the de.tobiasroeser.mill.spring.boot.SpringBootModule trait. The following targets are available:

def springBootToolsVersion: T[String]: Required. Override it to specify the version of the Spring Boot tools.
def springBootAssembly: T[PathRef]: Package an (executable) JAR.

You can run the application with java -jar out/app/springBootAssembly.dest/out.jar.
def springBootPrependScript: T[String]: A script prepended to the resulting springBootAssembly to make it executable. This uses the same prepend script logic as Mill JavaModule#prependScript does, so it supports most Linux/Unix shells (probably not fish) as well as Windows cmd shell (the file needs a .bat or .cmd extension in that case). Set it to "" if you don’t want an executable JAR.
def springBootMainClass: T[String]: The main class holding the Spring Boot Application entrypoint. By default, the value of JavaModule.mainClass is used, when defined, otherwise Spring Boot will try to auto-detect it.

Download

You can download binary releases from Maven Central.

Please make sure to use the correct mill platform suffix matching your used mill version.
