Almost each Scala version changes the way collection conversion happens in a non-backward compatible way. Is there a better solution that is version agnostic and does not depend on Scala distribution?
I don't mind using some 3rd party libraries.
Just use the scala-collections-compat library and then you can use import scala.jdk.CollectionConverters._ on Scala 2.11, 2.12 & 2.13.
