What IDEs are available for jRuby?

Question

I've done some googling and there seems to be a scarcity of IDEs for jRuby. I've read about TextMate and Sublime, but they don't provide debugging or code completion.

Can someone make a suggestion (or is this technology still in its infancy)?

Answer 1

There are several options; I prefer JetBrains' IntelliJ (RubyMine).

Aptana has an Eclipse plugin. NetBeans used to have official support, not sure what the current state is.
