A new version of rawr has been released.
Rawr is a tool for packaging JRuby programs into standalone applications. Rawr offered an option to fetch the most current jruby-complete.jar file. This stopped working when the JRuby team changed their hosting provider.
The last release of Rawr simply turned this option off, pending a fix. This new release has that fix.
One difference, though, is that whereas there used to a choice of “most recent” and “current stable” you now just get whatever is the latest release.
You can get the gem from the Neurogami gems page or install it using
sudo gem i rawr --source http://gems.neurogami.com
