This error occurs when a @static member in a companion object tries to override or implement a non-static member from a parent trait or class.
The @static annotation causes a member to be compiled as a JVM static member. Static members cannot participate in inheritance hierarchies because they are not part of instances and cannot be dynamically dispatched. Therefore, a @static member cannot override or implement abstract members from parent types.

trait Parent:
def value: Int
class Child
object Child extends Parent:
@static def value: Int = 42
-- [E132] Syntax Error: example.scala:9:14 -------------------------------------
9 | @static def value: Int = 42
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^
| @static members cannot override or implement non-static ones
// Remove the @static annotation to allow proper implementation
import scala.annotation.static
trait Parent:
def value: Int
class Child
object Child extends Parent:
def value: Int = 42
// Alternative: Don't extend the trait and use a different method name
import scala.annotation.static
trait Parent:
def value: Int
class Child
object Child:
