ah…If you put jruby.jar into your classpath (or in ant lib directory) then you need to set up GEM_HOME to point to a location where rake is installed. An easier way is to download the jruby-complete.jar which has rake embedded into it. It is larger, but should get rid of your problem. If not consider opening an issue on the jruby project (www.jruby.org) and we will help figure this out.

Is this available in the current release of jruby? For the example, I was getting the below error:

ant -v

I wonder if its possible to have ONE build tool, like Ant or Rake, which is language agnostic and supports, for example ruby, perl, C and Java

there's also a gem for integrating ivy into ruby: http://github.com/klaas1979/ivy4r

Dependency management is something we will tackle, but not for this first iteration. The boundaries of mixing ant and rake together is fairly clear. Dependency management is a little less straightforward (at least to me).

We do have some folks who are working on exposing all maven artifacts as Ruby gems, but this is only for retrieving a graph of dependencies and not specifying them.

" I was hoping to show that sometimes combining things together really is the best strategy" … yes an exact continuous integration approach :)

Nice thinking… I'm not at all a Java Person, but still it looks too much productive …

I would suggest taking this to the next step… this directly takes on Gant, but Gradle still does a lot more (dependency management)

Really nice post and features. It's everything I've wanted from ant+rake integration. And for those not in the know: it's also an incredibly small amount of code in JRuby, considering all it does: http://github.com/jruby/jruby/tree/master/lib/rub... and http://github.com/jruby/jruby/tree/master/src/org...
