Downloading JRuby Source and Building It Yourself

If you prefer to download JRuby source and build it yourself, rather than installing a binary as described in Getting Started with JRuby, you can either download the source files from our web site or get JRuby source code directly from our git repository.

To get JRuby source from the web in a tar or zip file, Download the latest JRuby Source .tar or .zip file and extract it to a directory. The instructions below assume you've extracted the file to the jruby directory.
- For OSX, Linux, BSD, Solaris, and other UNIX varieties, get the most recent jruby-src-X.Y.Z.tar.gz file.
- If you're on Microsoft Windows, get the most recent jruby-src-X.Y.Z.zip file.
To get JRuby source from our git repository, retrieve the trunk version of the JRuby source. For example, you can use the following terminal window or command window command to save the files to the jruby directory:
git clone git://kenai.com/jruby~main jruby.

Build JRuby using the following shell commands (Note: Ant 1.7 is required to build JRuby version greater than 1.1):
cd jruby ant
Create an up-to-date version of jruby-complete.jar with this ant task:
ant jar-complete
Generate an up-to-date set of the JavaDoc for JRuby located at docs/api/index.html:
ant create-apidocs (< Jruby 1.3.*) ant apidocs (>= Jruby 1.4.*)
Delete any build and compile artifacts:
ant clean
Run the JRuby tests:
ant test
