Add JRuby and Rubinius cases on Travis CI

[junaruga]

I just knew that rb-inotify is used with JRuby seeing issue page's user report. This PR must be useful to share issues of JRuby and Rubinius easily.

I added Rubinius (rbx-3) as allow_failures as it is sometimes unstable. This set of CRuby, JRuby and Rubinius in .travis.yml is typically used for some RubyGem packages.

Can you rebase on master?

I've never had rbx-3 work on travis- is it working now?

[junaruga]

Yes, I rebased it on latest master branch right now.

I've never had rbx-3 work on travis- is it working now?

Yes, I have never tried to run rb-inotify on rbx-3 too. But at least the rbx-3 is available on Travis CI. Please look at below case of unit-test project.

https://github.com/test-unit/test-unit/pull/145 https://travis-ci.org/test-unit/test-unit/jobs/231604875

$ ruby --version rubinius 3.77 (2.3.1 d8751792 2017-05-06 3.8.0) [x86_64-linux-gnu]

But there is a issue for all the Rubies right now in rb-notify.

I think that the rake test does not work seeing Travis log for maybe all the Rubies.

The reason is I suppose that Rake::TestTask.new does not work.

Referring below sample. rspec-core is reliable as rspec sample, isn't it? :) https://github.com/rspec/rspec-core/blob/master/Rakefile

After below modification on local, it works.

And one more thing, below files have executable bit (+x). It was not before rebase. I guess that it is your text editor's issue.

Oh god, yes, I think something went wrong with the samba file sharing. I have to develop this on my linux box and I'm in bed right now, I mount it via SMB, and the editor has foo barred everything. This is sufficiently ugly.. I may force push to fix this.

[ioquatix]

I've merged your changes, and I've rewritten history to fix the x bit. My apologies and thanks for catching it. It's 2AM so my bad.

[junaruga]

I am fine. No problem. Thank you for your work at midnight.

[ioquatix]

Okay, you were right, and it worked: https://travis-ci.org/guard/rb-inotify/builds/234325378

Last time I tried rbx-3 it didn't work, so that's awesome.

Okay, so now we just need a few more specs :)
