Reports declarations that are not used.

The quick-fix removes the unused declaration.

In the Options below, you can control if the inspection should work for public and/or local declarations. In case of local declarations, on top of enabling and disabling the inspection, you can also make it dependent on the existence of one of three compiler options: -Wunused:locals, -Wunused:linted, or -Xlint:unused.

Example:

  def test(): Int = {
    val unused = 3
    3
  }

After the quick-fix is applied:

  def test(): Int = {
    3
  }
