Best way to handle false unused imports in intellij

Intellij falsely marked some import of Scala implicits as not being use. Is there a way to prevent it from deleting those import when optimized them explicitly for a specific import and not prevent optimized import for the entire project ?

Solution

  • I'm afraid there isn't, I had similar issues especially when using akka and importing the implicit execution context from an ActorSystem in some cases. I recommend defining the value instead of importing. One such example would be:

    // Avoid importing the execution context like this
class MyActor extends Actor {
  import context.system.dispatcher
}

// Define it explicitly instead
class MyActor extends Actor {
  implicit val ec = context.system.dispatcher
}

    I hope this helps you.
