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