Eclipse scala "Could not find or load main class"

I have just started learning scala, i am using the eclipse ide for it, in the run configuration i have set scala application with the project name and as main class main when i compile i have

Error: Could not find or load main class main

when i check the console i see it's reading from Java/jre directory, is it normal or should i change that ? This is the code

package one

class Main {
object Bottles {
    def main(args: Array[String]){
        var n : Int=2;
        while(n<=6){
            println(s"Hello ${n} bottles");
            n+=1;
        }
    }
}
}

Okay, also had the same error Error: "Could not find or load main class main" in my Scala IDE and the reason of that was that when I created Main, I immediately moved it to a package.

So I had to:

  • Move my main class back to default package.
  • Clean, compile, run.

The main method needs to be on a toplevel object. Your Bottles object is wrapped in a Main class. Remove that Main class and your code should run.

object Bottles {
  def main(args: Array[String]){
    var n : Int=2;
    while(n<=6){
      println(s"Hello ${n} bottles");
      n+=1;
    }
  }
}
