Jruby require 'java' gives warning

Hello Charles,

Are you using RubyMine or the Ruby plugin?

RubyMine does not know, and is not going to know, anything about require
'java' or other JRuby-specific extensions. All of them are fully supported
only in the Ruby plugin.

In JRuby 1.2.0 (haven't checked other versions), require 'java'; gives
a warning that there is no such file to load.

Generally, the jruby rails environment does this for you, or some
other library pulls it in, but in a bare script you need to do it
yourself.

In any case, it should not be a warning.

I'm using RubyMine for a standalone JRuby project.


The libs in question are in
JRUBY_HOME/lib/ruby/site_ruby/1.8/builtin/javasupport

I was able to workaround it my explicitly putting it on my loadpath, but
it seems like if you know that a project is using JRuby SDK, then it
putting that directory on the loadpath is doable, since it is bundled
with JRuby.

In any case, I just explicity put it in the loadpath of the project as a
workaround.

cheers,
Charles
