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

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 开发者_如何转开发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.

One way in which creating .jar can be "simpler" is to use simple-build-tool, which supports the package* targets and requires rather little time to set up and use.

You could use the maven scala plugin or the buildr tool.

This has actually really helped

If you are using eclipse then just export your project as a jar file

goto file -> Export ->java -> as a jar file

Just bit more explanation:

1. Install the scala eclipse environment from typesafe
2. Once you are done coding, export as a jar (file -> Export ->java -> as a jar file)
3. from a command line you can run java -cp path_to_dependancies:your_newly_generated_jar:. your_main_object_name.

hth.
