type mismatch; found : edu.stanford.nlp.util.CoreMap => Unit required: java.util.function.Consumer[_ >: edu.stanford.nlp.util.CoreMap]

I don't understand what it wants from me. The assignment to sentence is working:

val sentences : java.util.List[CoreMap] = document.get(classOf[SentencesAnnotation])

but I can't run a forEach loop on this:

sentences.forEach( (s : CoreMap) => println("") )

since I am getting:

Error:(39, 38) type mismatch; found   : edu.stanford.nlp.util.CoreMap => Unit required: java.util.function.Consumer[_ >: edu.stanford.nlp.util.CoreMap]
sentences.forEach( (s : CoreMap) => println("") )
             ^

What is the problem here? s has a type given already.

You're using Java's forEach (which indeed expects a java.util.function.Consumer), did you mean Scala's foreach? foreach would work (if you import JavaConversions):

import scala.collection.JavaConversions._
sentences.foreach( (s : CoreMap) => println("") )
