How can I handle gems with a portable JRuby?

Question

We're using Ruby scripts for certain parts of a build. To execute them, we're using JRuby ( the complete jar ), and so far we haven't made use of any gems outside the stdlib. If for example, I would want use three gems from github, how would I approach this?

I know of Nick Sieger's Gems-in-a-jar article, but it's from 2009. Is it still the accepted way of doing this or did JRuby introduce another method of achieving the same result?

Answer 1

You can use gems-in-a-jar, or you can use Warbler to bundle JRuby and all your gems into a single executable jar.
