Warning "Following value requires an explicit type annotation" for values = findValues about enumeratum HOT 2 CLOSED

It works
Many thanks for the advice !

Hi there,

Good question. The problem is probably because you didn't have the immutable IndexedSeq imported (which is what is explicitly produced by findValues).

The following should work:

import enumeratum._
import scala.collection.immutable.IndexedSeq
  
sealed trait Greeting extends EnumEntry
  
object Greeting extends Enum[Greeting] {
  val values: IndexedSeq[Greeting] = findValues
  
  case object Hello extends Greeting
  
  case object Bue extends Greeting
  
  case object Hi extends Greeting
}

Also, I think in IntelliJ, when you have a warning like that, you can put your cursor on that part of the code and hit option+enter (on Mac, not sure of the equiv elsewhere. I also have settings carried over from super old IntelliJ) and choose "Add type annotation", which will automatically find the right one for you.

Let me know if you have any further questions.
