Rake + Ant + JRuby

==================

This shows how to compile a jar project using Rake and Ant running on JRuby. JRuby is started with nailgun

to improve task execution time with Rake.

IMHO this is a nice intersection of mature build tools, convenient build tasks, and a flexible language.

Startup time is also important. This could be used quickly from something like `gosh (the go shell)`_.

*Requirements*:

- Rake (``gem install rake``)

- Apache ANT, the ``ANT_HOME`` environment variable must be set

- JRuby

*Usage*:

.. code-block:: bash

  # start jruby using nailgun

  jruby --ng-server

  # root of ant tool

  export ANT_HOME="$HOME/tools/ant"

  # connect using nailgun client; --dev option to improve startup time (https://github.com/jruby/jruby/wiki/Improving-startup-time)

  export JRUBY_OPTS="--ng --dev"

  # run rake 

  rake ant:compile ant:jar
