how to make warbler compile ruby files with --javac?

Question

I'm using warbler to build a jar out of ruby classes so that it can be run as a interactive application. Now, I want to use that jar as a library in my java application. I've noticed that warbler generated jar contains ruby classes compiled using jrubyc without --javac option. So dows anyone know how to generate a jar using warbler so that it can be run as a standalone application as well can be used as a library in Java projects so that object of ruby classes can be created in Java?

Below is how my ruby code is structured:

core
    |--- lib
        |----a.rb
        |----b.rb
    |---java_lib

a.rb contents:

require 'b'
class A
    def test
        ob=b.new
        puts ob.test
    end
end

b.rb contents:

class B
    def test
        puts "test"
    end
end

Then, I've created a jar of above using warbler, put a jar in classpath of another java project and tries to access a.test. But it says "unable to load -- b"

Answer 1

Warbler does not currently allow you to pass that option. I see that you have already opened an issue about this. Beyond that, your best bet would be to try hacking the line of code that invokes jrubyc to add the option and see how things fail.

I don't run the Warbler project, but it's my opinion that this is not the point of Warbler, so you may just want to write a Rakefile (or Makefile, or POM, or whatever) that runs jrubyc and creates the JAR for you.

In addition, your updates to the question focus on the unable to load -- b problem, which is completely unrelated to the original question, and I believe I have answered that in your other question.
