E116: Missing Companion for Static

This error is emitted when an object contains @static members but does not have a companion class.

Objects with @static members must have a companion class because the static members are placed in the companion class's bytecode.

Example

scala

import scala.annotation.static

object Example:
  @static val count = 0
