jruby bash scripts do not work with msys/mingw
----------------------------------------------
Key: JRUBY-5864
URL: http://jira.codehaus.org/browse/JRUBY-5864
Project: JRuby
Issue Type: Bug
Components: Launcher, Windows
Affects Versions: JRuby 1.6.2
Environment: Windows 7 running msys git
Reporter: Ryan Bergman
Assignee: Thomas E Enebo
I'm having an issue executing jruby from the mingw git bash shell in windows. I
downloaded the windows installer for jruby 1.6.2 and ran it without issue. If I
open a new windows cmd shell it seems to work fine. I installed the rake and
sinatra gems; used the irb. entering jruby -v gets:
jruby 1.6.2 (ruby-1.8.7-p330) (2011-05-23 e2ea975) (Java HotSpot(TM) Client
VM 1.6.0_24) [Windows 7-x86-java]
However, when I open the git mingw bash shell and attempt to do anything with
jruby I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/jruby/Main
Caused by: java.lang.ClassNotFoundException: org.jruby.Main
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: org.jruby.Main. Program will exit.
I think the issue is the shell scripts that end up invoking the jar in the
jruby bin directory.
The issue is that while msys can transform POSIX to Win paths for most things,
but the script builds up strings on its own in order to pass classpath and
other information to the jar.
It appears that this is where things are getting messed up. The scripts
specifically have branches of code that deal with cygwin for this same reason.
I attempted to force the scripts to to think that it was running under cygwin
but unfortunately the scripts make use of the "cygpath" program to get the
paths and that is not available in msys
