Basically, IntelliJ IDEA is a Java-related IDE for developing software developed by JetBrains. Here we discussing how to install Scala plugin in IntelliJ IDEA on the Ubuntu operating system.

For, first time users in IntelliJ IDEA we checked whether Scala Plugin is available or not. But here is Scala is not available.

Getting Scala version for Sbt, downloading Maven Repos from scala official website then it showing [SUCCESSFUL] in IntelliJ IDEA console. It will take some more time to set up the Scala project structure and get external library files for Java, Scala from the internet.
