How can I create a jar from some Scala source code?

Question

How can I create a jar from some Scala source code? I want to use some of that code in a Clojure project of mine.

Is there a simpler way than doing batch files as in this SO question?

Thanks, Alex

Scala is in no way special when it comes to what you do with the .class files produced by its compiler. Just use the jar command with the c action flag.

However, you will need to have the scala-library.jar file in the class-path when you run the program that uses the Scala-compiled .class files. And be careful to use the scala-library.jar for / from the same Scala Development Kit that you used to compile the Scala source. As of yet, there isn't inter-version binary compatibility for Scala-generated .class files.
