1. Create project

File > New > Project > Maven 1.1 Add directory src/main/scala src/test/scala

##2. Edit pom.xml

    <groupId>com.freepsw</groupId>
    <artifactId>java_scala</artifactId>

    <packaging>jar</packaging>

    <dependencies>
        <dependency>

            <artifactId>scala-library</artifactId>
            <version>2.11.8</version>
        </dependency>

    <build>
        <plugins>
            <plugin>

                <artifactId>scala-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>scala-compile-first</id>
                        <phase>process-resources</phase>
                        <goals>
                            <goal>add-source</goal>
                            <goal>compile</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>scala-test-compile</id>
                        <phase>process-test-resources</phase>
                        <goals>
                            <goal>testCompile</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

추가된 directory의 색상이 java와 같은 색상으로 변하지 않을 경우, maven update를 해 주면 적용됨. Intellij에서는

File > Settings > Build,Execution,Deployment > Build Tools > Maven > Importing을 클릭

• Import Maven projects automatically 항목을 check

3. Create Scala Object adn Run

3.1 Create TestScala.scala

object TestScala {
  def main(args: Array[String]) : Unit = {
    println("Helo Scala")
  }
}

3.2 click right button of mouse "Run TestScala"가 보이면 성공.
