----------------------------------------------------------------------
Key: JRUBY-3487
URL: http://jira.codehaus.org/browse/JRUBY-3487
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.2
Reporter: Roy Tinker
Assignee: Thomas E Enebo
Priority: Minor
Fix For: JRuby 1.2
I am trying to follow Nick Sieger's instructions for packaging and using gems
as Jar files at:
http://blog.nicksieger.com/articles/2009/01/10/jruby-1-1-6-gems-in-a-jar, but I
am running into problems.
Here is a transcript of my session, with comments denoted by {{REM}}:
{{
