2) cd helloworld
3) create a file build.gradle

apply plugin: 'scala'
apply plugin: 'eclipse'


    compile 'org.slf4j:slf4j-api:1.7.5'
    compile "org.scala-lang:scala-library:2.11.2"
    testCompile "junit:junit:4.11"

task run(type: JavaExec, dependsOn: classes) {
    main = 'Main'
    classpath sourceSets.main.runtimeClasspath
    classpath configurations.runtime
4) in the folder helloworld, run the following commands
gradle eclipse
5) Import the project to eclipse
6) Every time you add new dependencies, remember to run gradle eclipse so that the libraries references in eclipse settings are updated accordingly.

object Main extends App {
	println("Hello World");
