Jerome posted the
instructions to build

GlassFish v3 Gem for JRuby - very simple and easy. A binary version of Gem
is available

here.

1. Software pre-requisite
   1. Subversion client (for example
      Tigris)
   2. Maven 2.0.x
   3. JRuby 1.0.x (I used
      JRuby 1.0.2
      and lets say installed in JRUBY_HOME).  Make sure
      JRUBY_HOME/bin is in your path.
2. Build the Gem

   1. As explained in
      Jerome's
      entry, you can check out complete GlassFish v3 workspace or just the
      Gem code. Here is how you'll check out only the Gem code on a Windows
      machine using Tigris Subversion client:
      
      
      
      
      
      
      
      And after the check out is complete, you'll see:
      
      
      

   2. Build the gem by giving the command:
      
      
      
      mvn install
      
      
      
      And success is achieved by seeing the following in the console:
