This page shows how to start with Scala using Eclipse
First you need to have Eclipse installed on your computer, for information about Eclipse and how to install it see this page.
From within Eclipse menu goto:
help -> software updates -> available software
Click on 'Add Site'
Into Location enter:
http://www.scala-lang.org/scala-eclipse-plugin
and click on 'OK'
select 'Scala Eclipse Plugin' and click on install
Click next and accept terms.
New Scala Project
To start a scala project choose New project from menu
click on next and enter project name:
Click on Finish, that will give us a project node and under that a 'src' node in the package explorer, in the window on the left.
Right click on the 'src' node and create a new Package.
Give it a name and click on finish.
Right click on the package node (which I called hello1 in this example). create a new scala object, name it, and click on finish.
We can then enter a simple scala program into this object.
To run it choose Run -> runAs from the menu. Select 'Scala Application' (not 'Run on Server' as shown above).
The program runs: in this case a message appears in the console.
