= Ruby2Jar - build JAR from Ruby script

Ruby2Jar builds JAR from a Ruby script. It copies gems, compiles sources

and packages JAR. It is an easy way to distribute your JRuby application or 

create Applet or Java Web Start.

== Installation

Use Gem to download and install Ruby2Jar.

   gem install ruby2jar

You must have Java Development Kit to use JAR builder. Also you should run it 

from JRuby for correct platform in gems.

== Usage

Add task to build JAR in Rakefile:

  require "rubygems"

  require "ruby2jar"

  

  PKG_NAME = "program"

  PKG_VERSION = "0.1"

  

  Ruby2Jar::Rake::JarTask.new do |jar|

    jar.files = FileList["lib/**/*", "bin/*"]

    jar.main = "bin/program"

    jar.name = PKG_NAME

    jar.version = PKG_VERSION

    jar.add_dependency "rspec"

  end

== Limitation

In current JRuby version (1.1.2) you can't use Ruby file system functions 

and +__FILE__+ constant in JAR. So didn't use Dir.glob to require 

all files in dir or somethink like this.

If program containt Java files it must be in ext/ dir. Source Java files 

without class files will be compiled.

== Gem config

Gem can contain building config java.yaml in gem root. Builder will 

find list of exclude file patterns in jar.exclude config node.

== License

Ruby2Jar is licensed under the GNU General Public License version 3.

You can read it in LICENSE file or in http://www.gnu.org/licenses/gpl.html .
