When I try to use rawr on Windows, I get this:

=== Creating jar file: C:/Users/Alex/Documents/Projects/hello_world/package/jar/ChangeMe.jar
rake aborted!
stat.st_gid unsupported on this platform

It looks like the version of rubyzip bundled with rawr has a malfunctioning test for Windows:

RUNNING_ON_WINDOWS = /mswin32|cygwin|mingw|bccwin/ =~ RUBY_PLATFORM

That’s bound to fail on jruby:

C:\Users\Alex\Documents\Projects\hello_world>jirb
irb(main):001:0> RUBY_PLATFORM
=> "java"

I’m not sure what the “official” fix for this is; I’ll post an update once I’ve figured it out.

Update: I don’t know if it’s in any way proper, but editing the above test in %JRUBY_HOME%/lib/ruby/gems/1.8/gems/rawr-1.1.0/lib/zip/zip.rb to read:

RUNNING_ON_WINDOWS = (/mswin32|cygwin|mingw|bccwin/ =~ RUBY_PLATFORM) ||
	  (/Windows/ =~ ENV['OS'])

seems to allow the jar file to be built, and the executable file to be generated, but it doesn’t actually run. Hm. More work needed here.

Further Update: There’s a better fix in rawr’s gitorious repository for this now using rbconfig. I’m still working (with Logan Barnett’s sterling help) on getting it working.
