테스트 소스
HelloScala.scala

package com.babukuma.scala

object HelloScala {

  def main(args: Array[String]): Unit = { 
  println("Hello Scala!")
 
  val helloJava = new HelloJava
  helloJava.printHelloJava()
  }
}

HelloJava.java

package com.babukuma.scala;

public class HelloJava {
  public void printHelloJava() {
    System.out.println("Hello Java!");
  }
}

컴파일과 패키징

$ mvn compile
$ mvn package

실행

$ mvn scala:run -DmainClass=com.babukuma.scala.HelloScala
Hello Scala!
Hello Java!
