Running cucumber on jruby under ant.
George Dinwiddie
Twitter, Aslak suggested here.
I've been struggling here trying to run cucumber on jruby under ant. It
all works so well on the command line, but I'd like to integrate it into
a build script.
After a number of trials, I've come closest with the ant target shown as
'cuke4.xml' in https://gist.github.com/1782945 Unfortunately, that gives
me the Gem::LoadError shown in 'cuke4.output'
So, to investigate where jruby was looking for gems under ant, I wrote
the target in 'gempath.xml' and got the output shown as 'gempath.output'
That kinda stumped me.
Can anyone explain what's going on here? Or, more directly, can anyone
suggest how to run a ruby program using jruby under ant? I seem to be
missing an essential piece of information.

So you're trying to tell Jruby where to find the Gems that you've got
installed?
set the environment variable GEM_PATH, jruby will honor that to look for
gems in wherever that path is.
I know this isn't ant, but there are ant calls in this Maven project
that's referencing gems, perhaps it'll help you some:
https://github.com/dkowis/Cucumber-JVM-Ruby-Example
it uses ant to call jruby to install bundler, and then call bundle
install using a Gemfile in the root of the project.
I think it should cover the things you're wanting to do, unless I'm not
understanding.

I never figured out how to set this from Ant such that jruby would find
it. And sanitizes the environment for processes it calls--perhaps a bit
too much.

That seems complicated for my needs. I don't really want the complexity
of bundler and re-installing gems in the build file just to run some
cucumber tests on a java project.
I went back to my simple beginnings, though, and after stumbling across
the way to read the OS environment values within ant (I had thought they
were automatically available, but either I misremembered or that changed
at some point.), I ended up with the following:
<target name="cucumber" description="Run the cucumber tests">
<property environment="env" />
<exec executable="cucumber" >
<env key="PATH" path="${env.PATH}:${jruby.home}/bin" />
<env key="CLASSPATH" file="${jruby.home}/lib/jruby.jar" />
</exec>
</target>
which works fine. I like it; it's fairly simple and tidy.

Except it doesn't work under Eclipse, which also messes with the PATH. I
modified it to the following:
<target name="cucumber" description="Run the cucumber tests">
<property environment="env" />
<exec executable="${jruby.home}/bin/cucumber" >
<env key="PATH" path="${jruby.home}/bin:${env.PATH}" />
<env key="CLASSPATH" file="${jruby.home}/lib/jruby.jar" />
</exec>
</target>

Yeah, I didn't intend for you to use bundler and all that, just as an
example that works :)

Works for me :)
