Scala runtime library module for Terasology.

Scala Runtime Library Module

The Scala Runtime Library Module (or short ScalaLib module) includes the scala runtime library. Therefore, it allows for modules to be written in Scala (see www.scala-lang.org).

scalalib's Issues

Best way to use ScalaLib?

Is the ideal way to use this module as a dependency for other modules, or as a template for modules that intend to use Scala?

If the former, it might be useful to allow authors to configure/override this line in order to specify the lib version:

    includeInJar 'org.scala-lang:scala-library:2.11.7'

I don't know much about gradle, so any suggestions would be appreciated. Thanks!

Trouble loading scala library

I'm not sure if this is a result of the scala library being a nested jar within the module jar. Are there any other examples of how to handle external dependencies in modules?:

I also tried adding the following to the PACKAGES whitelist inengine/src/main/java/org/terasology/engine/module/ExternalApiWhitelist.java but this didn't seem to help:

            .add("scala.lang")
            .add("scala.collection")
