Scala With Eclipse

Removing a broken plugin

If you have a Scala plugin installed and it doesn't work, it's probably a good idea to remove it first. Run Help > Software Updates > Manage Configuration..., select the feature of interest, and disable it with the task shown in the right window.

Installing the Scala plugin

• In the Eclipse menus, go to Help > Install New Software.

• Click on the Add button and add a new site with Name "Scala" and Location http://download.scala-ide.org/nightly-update-wip-exp-backport-2.8.1.final

• Select all three available pieces of software in the dialog box and click on the Next button.

• Accept the license agreement.

• Click on the Finish button.

• If Eclipse asks you if you want to restart now, say Yes.

Testing the plugin

• Go to File > New > Scala project in the menus.

• Give your project a name and click on Finish.

• In your project, go to File > New > Scala Object in the menus and create a new object called Hello

• In the object, add the following method:

 
def main(args: Array[String]) : Unit = {
    // println() prints a string to the console.
    println("Hello world!")
}
  

• Click the Run button and if everything is working you should see 'Hello World!' printed in the console.
