Scala 2.12: Compile error - type PlainNioFile is not a member of package scala.reflect.io

Question

I'm trying to compile my spark scala application and getting below error. Same code was working fine with scala 2.11 version.

I did look at this solution and tried adding scala-reflect as the dependency but still getting the same error. I do see scala-reflect is added as dependency

Can't import scala.reflect.runtime.universe

Scala version 2.12.10
