The error message indicates that Ruby 2.1.0 is running, not JRuby.

Whatever setup is running is not using JRuby for this rake command.

What happens if you run this command
ruby -v
Does the Ruby version indicate "jruby"?

How about this command:
which rake

Hi Bruce,

Naresh -

Those look fine. I forgot to ask you for "which bundle", since you are
using "bundle exec rake ..."

Hi Bruce,

Here is the bundle info which I am using

(See full trace by running task with --trace)
test@pts00433-vm8:~/Travis/travis-logs$ which bundle
/usr/bin/bundle
test@pts00433-vm8:~/Travis/travis-logs$ bundle -v
Bundler version 1.6.3
test@pts00433-vm8:~/Travis/travis-logs$ whereis bundler
bundler: /usr/bin/bundler
test@pts00433-vm8:~/Travis/travis-logs$ whereis bundle
bundle: /usr/bin/bundle /usr/share/man/man1/bundle.1.gz

Naresh -

And that is the problem. You need to be using a bundle within JRuby.

I can hope that "which gem" shows a path under your .rvm directory with
jruby-1.7.16 in the path. If that is true, then "gem install bunder"
should get the correct "bundle" onto your path (so "which bundle" will
also show a path under .rvm/.../jruby-1.7.16/...)

If "which gem" shows a system "gem", such as /usr/bin/gem, then a simple
"gem install bundler" won't do what you need. You'll need to track down
the "gem" command associated with your JRuby and use that.
