JRuby: import vs include vs java_import vs include_class

Question

why so many different ways to include Java classes into JRuby? What are the differences? Which one should I use?

Answer 1

import doesn't play well with Rake, so it's discouraged. java_import is the newest, and recommended. include_class has been deprecated. Apart from that they all do the same thing, and are actually aliases of each other.

import is an alias for java_import and java_import calls include_class.
