pivotal-tracker can run in jruby

[joelash]

Replaced happymapper with nokogiri-happymapper and made some necessary changes around support that. All tests pass in jruby-1.6.7, jruby-1.7.0.preview2 and ruby-1.9.1+

Hey, was wondering what your thoughts about merging this were? It'd be beneficial to me at work if I could use a version of pivotal-tracker that runs independent of ruby platform. Thanks.

@joelash, I cherry picked 76d9c87 and rebuilt the gemspec via our automated tools. Your changes have been pushed as version 0.5.7. Thanks for the contribution, let us know if you see any issues.

I had to revert this commit because 0.5.7 didn't load properly under MRI. Release 0.5.8.

Hi,

I was reviewing the gemspec and I found that there is still a runtime dependency for Nokogiri 1.4 and I was wondering: - is this dependency needed?

I want to use this gem under JRuby but it keeps trying to install libxml-ruby, I will try to fin a way to deal with this and come back with a pull request.

Cheers!

We should not be bound to any particular version of nokogiri. Please test the removal and verify everything still functions properly and we can pull that in.

Can this be merged in if it is still passing? Happymapper dependency is limiting us from using the gem on JRuby.

@pivotal-casebook can you pull and merge in the lastest master? I can pull in the change.
