So what does it do?

It's an Ivy-compatible proxy for RubyGems, which translates gems into JRuby-compatible JARs.

This tool is for people who:

• Are working with the Java tool chain: good ol' javac, Maven, Ivy, Ant, Buildr and IDEs
• Want to use some (J)Ruby
• Want to use gems from RubyGems
• Don't want to use multiple VMs (JVM and CRuby)
• Don't want to hand-roll a GemJar everytime their ruby deps change
• Don't want to use two dependencies management tools (Bundler + Ivy)

I'm hoping thats not just me...

Trying it out -- GemJars.org Hosted

Gradle

1. Add to your repositories:

repositories {
    ivy {
        url 'http://repository.gemjars.org'
        layout 'pattern', {
            artifact 'jars/[organization]/[module]-[revision].jar'
            ivy 'ivys/[organization]/ivy-[module]-[revision].xml'
        }
    }
}

2. Add to your dependencies:

dependencies {
    compile 'org.rubygems:rspec:2.11.0'
}

3. Perform a gradle dependencies and watch it resolve rspec and all its transitive dependencies

Ivy

1. In your ivysettings.xml, set up the following resolver:

<ivysettings>
  ...
  <url name="gems">
    <ivy pattern="http://repository.gemjars.org/ivys/[organization]/ivy-[module]-[revision].xml" />
    <artifact pattern="http://repository.gemjars.org/jars/[organization]/[module]-[revision].jar" />
  </url>
  ...
  <chain name="default">
    ...
    <resolver ref="gems" />
  </chain>
</ivysettings>

2. In your ivy.xml, add a dependency from org.rubygems.

<ivy-module version="2.0">
  <dependency org="org.rubygems" name="cucumber" rev="1.0.0" />
</ivy-module>

3. Perform an ivy resolve and watch Ivy resolve cucumber and all its transitive dependencies.

Trying it out -- DIY

1. Clone the repo:

$ git clone git://github.com/akiellor/gemjar.git

2. Get Gradle

brew install gradle

OR

Get it from gradle.org.

3. RUN IT:

$ gradle run 

4. Hit some urls:

$ curl -i http://localhost:8080/jars/org.rubygems/cucumber-1.0.0.jar
$ curl -i http://localhost:8080/jars/org.rubygems/cucumber-1.0.0.jar.md5
$ curl -i http://localhost:8080/jars/org.rubygems/cucumber-1.0.0.jar.sha1
$ curl -i http://localhost:8080/ivys/org.rubygems/ivy-cucumber-1.0.0.xml
$ curl -i http://localhost:8080/ivys/org.rubygems/ivy-cucumber-1.0.0.xml.md5
$ curl -i http://localhost:8080/ivys/org.rubygems/ivy-cucumber-1.0.0.xml.sha1

4. Add the Gradle configuration or Ivy configuration as above.

Where's it at?

THIS IS A PROTOTYPE

DONE-ISH

• Construction of jruby compatible gemjars.
• Construction of ivy modules based on the gemspec.
• MD5 and SHA1 of all constructed artifacts.
• Can be built as a war.

SOON-ISH

• Maven pom.xml generation.

HOW CAN YOU HELP

• Try it out.
• Give me feed back.
