I can find tons of examples but they seem to either rely mostly on Java libraries or just read characters/lines/etc.

I just want to read in some file and get a byte array with scala libraries - can someone help me with that?

Java 7:

import java.nio.file.{Files, Paths}

val byteArray = Files.readAllBytes(Paths.get("/path/to/file"))

I believe this is the simplest way possible. Just leveraging existing tools here. NIO.2 is wonderful.
