Where can I find a bundle to install a development instance of Bonita in Eclipse?

Hi:

I’d like to use Bonita in a new project, but my main application will be based on J2EE technologies, I found an eclipse puglin for Eclipse Luna, but I couldn’t install it well, so I need a document that explains me how to configure a new development environment to work the application and the BPM process modeler on eclipse.

Best regards.
