title: Facing issue while trying to enable source code in IntelliJ for scala
body: <p>I am new to Scala programming and I have just started with basic programs in scala in IntelliJ IDE.</p>
  
  <p>When i use the below code</p>
  
  <p>package com.allaboutscala.chapter.one.tutorial_04</p>
  
  <p>object HelloWorld extends App{
    println("hello from hello world")</p>
  
  <p>}</p>
  
  <p>I wanted to see the source code of App where it uses the main method, but when i tries to see the source code and when I try to download it, I am getting error like 
  Sources not found: Sources for 'scala-library.jar' not found. I have attached the screenshot also.It would be great if someone could guide me here.</p>
