Ubuntu 18.04.4 LTS using snap.
I have sbt 1.3.13, Scala 2.13.3, and JDK 1.8.

Singleton object are created lazily

An object is a class that has exactly one instance. It is created lazily when it is referenced, like a lazy val.

so you have to actually call the object after creating it like so

object simple_test {
  val s = 4
  println(s)
}
simple_test

This should now output something like

4 res0: simple_test.type = simple_test$@3e32d495

This is similar to what happens in the following snippet

lazy val x = {
  val s = 4
  println(s)
}
x
