Any suggestions on what to try next?

Hello Sam,

I`m not sure, but it seems that you try debug your rails applicarion not within IntelliJ IDEA, please try debug your rails application.

It seems you've installed ruby-debug-base 0.10.2 instead of 0.10.1. Try the following configuration

Thanks Roman that combination of gems is working for me now!

The only thing that is not working is the visual following (highlighting) of the code in the IDE as I step through.
Do I need to configure something or is that a bug?

Sam,

I've also checked it. It doesn't work with JRuby interpreter but on Matz's interpreter all is ok. It seems something is broken in ruby-debug-ide gem for JRuby - we will check it.

I'm having a similar problem. I'm running jruby 1.1 on a windows machine with the following gems:
ruby-debug (0.10.1)
ruby-debug-base (0.10.1)
ruby-debug-ide (0.2.1)

When I try to launch the debugger from within IDEA I get a "Debugger not started" message box error. I tried to run it from command line and I get this:

C:\my-app>jruby -J-Djruby.reflection=true -J-Djruby.compile.mode=OFF -S rdebug script/server
C:/dev/jruby-1.1/lib/ruby/gems/1.8/gems/ruby-debug-0.10.1/cli/ruby-debug.rb:82:in `start_control': Debugger is not started (RuntimeError)

from C:/dev/jruby-1.1/bin/rdebug:19:in `load'
from C:/dev/jruby-1.1/bin/rdebug:19

Any idea?

I realize this is not an IntelliJ issue per se, but any help would be appreciated

You JRuby is out of date. Try JRuby 1.1.5 (last released version) or JRuby 1.1.3. See http://jruby.codehaus.org/
