JRuby Heroku Gem

Question

Is it possible to use Heroku client with JRuby?

I have installed heroku gem successfully with all dependencies, but I can't login.

    Command:     heroku login

PS D:\Projects\myproject>

Would appreciate any help.

Answer 1

I think I had the same problem with OpenSSL and JRuby (ruby 1.9.2) incompatibility. If you just want to login, try

JRUBY_OPTS=--1.8 heroku login

This will use the 1.8.7 version of ruby implementation of jruby which should work with OpenSSL

Edit: For windows

set JRUBY_OPTS=--1.8

heroku login

set JRUBY_OPTS=--1.9

Edit:

As of

heroku-toolbelt/2.30.5 (java) ruby/1.9.2

I no longer have this problem.

Note: Heroku recently announced official jRuby support and there is a dedicated help document on migrating exisiting apps to jRuby.
