Creating a jar file from a Scala file

Question

I\'m new to Scala and don\'t know Java. I want to create a jar file out of a simple Scala file. So I have my HelloWorld.scala, generate a HelloWorld.jar.

Manifest.m

Answer 1

Because Scala scripts require the Scala libraries to be installed, you will have to include the Scala runtime along with your JAR.

There are many strategies for doing this, such as jar jar, but ultimately the issue you're seeing is that the Java process you've started can't find the Scala JARs.

For a simple stand-alone script, I'd recommend using jar jar, otherwise you should start looking at a dependency management tool, or require users to install Scala in the JDK.
