Scala JavaConverters doesn't seem to work with collections returned by static methods

Question

I'm using a Java library from inside Scala 2.11 code. This Java library has a static load method that returns a Map<String,String> . Example usage in Java:

Map<String,String> map = Environment.load("dev");

I'm trying to get it working in Scala like so:

import scala.collection.JavaConverters._

val map : Map[String,String] = Environment.load("dev").asJava

And I'm getting a compiler error:

" Cannot resolve symbol asJava "

Any ideas?

Answer 1

Use asScala instead of asJava :

import scala.collection.JavaConverters._

val map: Map[String, String] = Environment.load("dev").asScala.toMap
