Forum: JRuby Trouble making .jar command failed with status (127)

I know this is probably a dumb mistake, but can someone help me?  Any
time I try to use as "rake rawr:jar" i get the error

javac -target 1.6 -cp
lib/java/jruby-complete.jar;lib/java/monkeybars-1.04.jar;src;lib/ruby
-sourcepath src;lib/ruby -d package/classes/java
src/org/rubyforge/rawr/Main.java
rake aborted!
Command failed with status (127): [javac -target 1.6 -cp
lib/java/jruby-comp...]

anyone know whats happening here?  I read this guys advice
http://groups.google.com/group/rawr-lib/browse_thread/thread/485828a8bc53da55
but the only problem is, I get the problem even when I don't edit the
files. :/

You might do better to grab the current code form the github repo.
There have been changes to jruby that broke how rawr was doing
compilation and such, making it explode.  That's fixed in trunk.

I hadn't used rawr for a while because I had my own fork, and because I
was largely working on older code that used earlier jruby jars.

When I took over as rawr-meister I poked around a bit and the most
notable error  was getting during code compilation.  JRuby had changed
the naming of some classes/modules used to invoke the complier, which
broke rawr.

gioele's fix for this should allow for compiling with both 1.4 and 1.5.
   If the  error you're getting is relate to compilation, then there's a
bug; you should have to drop to an older JRuby.

If the error is something else I don't know if changing JRuby versions
will help (but I'd be interested to know if it does).

Had the same error today.  Adding the jdk bin directory to my path 
solved my problem
