How to suppress Scalastyle warning?

I got following code:

    string match {
      case Regex(_, "1", "0", _, _)    =>
      case Regex(_, "1", "1", null, _) =>
    }

Scalastyle is complaining about usage of null which cannot be avoided here. Any way I can suppress warning just for this line?

Solution

  • Scalastyle understands suppression comments:

    // scalastyle:off <rule id>
...
// scalastyle:on <rule id>

    Rule ids are listed here

    In your case, the id is simply null:

    // scalastyle:off null
...
// scalastyle:on null
