Getting JRuby and Autospec to work
In order to get JRuby and script/autospec to work with in a Rails app you need to do a bit of hacking on your own. The basic problem is the autospec script attempts to call the autotest executable located in /usr/bin or /usr/local/bin from the command line through a system call. That script by default uses the ruby and not the jruby executable within your local environment. This will obviously fail. Instead I went ahead and copied the contents of the autotest script into script/autospec so everything runs nice and smooth with a jruby environment. Here is my script:
#!/usr/bin/env jruby
gem ‘test-unit’, ‘1.2.3’ if RUBY_VERSION.to_f >= 1.9
ENV[‘RSPEC’] = ‘true’ # allows autotest to discover rspec
ENV[‘AUTOTEST’] = ‘true’ # allows autotest to run w/ color on linux
require ‘rubygems’
version = “>= 0”
if ARGV.first =~ /^_(.*)_$/ and Gem::Version.correct? $1 then
version = $1
ARGV.shift
end
gem ‘ZenTest’, version
load Gem.bin_path(‘ZenTest’, ‘autotest’, version)
Now simply run ./script/autospec while you develop and autotest will work as it did before. Make sure you have the ZenTest and autotest-rails gems installed into your JRuby environment (using jgem).

I snuck into the conservative’s conference while at Netroots Nation. A lot of the conversation focuses on the audience’s love of DDT (yes the chemical).
