That's formatting error. This should be fine:

object JDWhileLoop
{               
                def main(args: Array[String]) 
                {
                        var index:Int = 0
                        while( index<=10) {
                        println("index="+index)
                        index= index+1           
                        }
                }       
}

In your code def main(args: Array[String]) treated as an abstract method (without body) followed by some code block in object inner body definition.

Note that in scala the following braces style is preffered

def foo (args: Bar) {
  //some work 
}
