Using Scala in Eclipse - Windows

Scala is Programming Language that supports Functional Programming. Scala source code is intended to be compiled to bytecode, resulting in flexibility to be run on Java Virtual Machine.In order to work on Scala, you need to have the following tools installed on your machine:

• Java Development Kit (JDK)
• Scala Build Tool (SBT)
• Editor such as Eclipse,Intellij IDE or any other IDE of your choice

Check whether you have Java installed by typing in the console:

java

or check the latest version

java -version

If not installed then download java from the Oracle website ,run installer and include bin directory of installed JDK in Path environment variable as explained here.

Download SBT tool from here. Run the installer and include the bin directory (usually located under C:\Program Files\sbt\bin) in Path environment variable. Check if installed by typing in console

sbt

you will see something like 

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

[info] Set current project to Users (in build file:/C:/Users)

Also you can find the folder .sbt installed under C:\Users\User_Profile\.sbt

Lastly we focus on choosing IDE. Mostly recommended is Intellij IDE as it showcase the environment to run Scala application, but here I will spotlight on using Eclipse.

For Scala we have two options to use Eclipse, 1) either use any existing eclipse IDE (Kepler onwards is preferred as Scala plugin is not supported below Kepler) or 2) use Scale IDE for Eclipse which is very easy - download and use in 2 minutes.

If using regular Eclipse, choose Help/Install => New Software and paste the URL http://download.scala-ide.org/sdk/lithium/e46/scala211/stable/site. You would be provided with the options to install Scala for Eclipse IDE, accept it and download completes. Eclipse will restart.

Now you can create new Scala project if you find the Scala related options under File =>New

Good job guys 😊, Hope this blog helps you !!!
