running all tests of vert.x on a gentoo box

so after setting up the dev environment (btw. IDEA setup was much smoother) I wants to run all tests via

$./mk test

After getting errors like:

Exception in Ruby verticle: no such file to load -- rubygems

or

Exception in Ruby verticle: no such file to load -- json

I figured out that I have to install ruby and jruby properly on my Gentoo box. In short, run the following commands:

$sudo emerge -va dev-java/jruby dev-ruby/rubygems dev-lang/ruby
$sudo eselect ruby set ruby19
$sudo jruby -S gem install json

and add the following lines to your ~/.bashrc

...
export JRUBY_HOME=/usr/share/jruby
export RUBY_HOME=/usr/lib64/ruby/1.9.1
...

Don’t forget

$source ~/.bashrc

I used

$equery files jruby

and

$equery files ruby

to find the right directories.

Result:

$~/mk test

...

Information: Starting test: test_echo_binary

:test
