cd to an empty folder. Run the following command sbt new scala/hello-world.g8. This pulls the ‘hello-world’ template from GitHub. It will also create a target folder, which you can ignore. When prompted, name the application hello-world. This will create a project called “hello-world”. Let’s take a look at what just got generated:

• hello-world
  • project (sbt uses this to install manage plugins and dependencies)
    • build.properties
  • src
    • main
      • scala (All of your scala code goes here) -Main.scala (Entry point of program) <-- this is all we need for now build.sbt (sbt's build definition file)

cd into hello-world. Run sbt. This will open up the sbt console. Type ~run. The ~ is optional and causes sbt to re-run on every file save, allowing for a fast edit/run/debug cycle. sbt will also generate a target directory which you can ignore. Modifying the code Open the file src/main/scala/Main.scala in your favorite text editor. Change “Hello, World!” to “Hello, New York!” If you haven’t stopped the sbt command, you should see “Hello, New York!” printed to the console. You can continue to make changes and see the results in the console.

Open up build.sbt and add the following line: libraryDependencies += "org.scala-lang.modules" %% "scala-parser-combinators" % "1.1.0"
