JRuby 1.1.x + Merb = Not generating the app

Ruby JRuby
1

I tried generating a template Merb (0.9.3) app using JRuby 1.1.1 and 1.1
as:

bin/jruby -S merb-gen app hello

and the command returns without generating any files or error message.

What’s missing ?

It works for me on 1.1.1. Do you have the merb-gen gem installed?

Arun,

I just did a clean install of JRuby 1.1.1, Rails 2.0.2, Merb 0.9.3, and
all
dependent gems. I ran the same command you did with the only difference
being that I have JRuby in my $PATH variable so I can just run “$ jruby
-S
merb-gen app merbtest”

I also have Java 1.6 (soy latte) installed and in my path as well. I
don’t
know if that would make a difference…

Reviving this thread …

I tried with different versions of JRuby (1.1, 1.1.1, 1.1.2) and Java
(JDK 1.5.0, 1.6.0_05) and still not able to generate a simple Merb app.

Another user reported similar error at:

http://blog.nodeta.fi/2008/05/22/living-on-the-edge-jruby-merb-glassfish/

How do I debug ?

Arun, it’s working fine here:(OS X 10.5)

$ jruby -v
ruby 1.8.6 (2008-04-22 rev 6555) [i386-jruby1.1.1]
$ jruby -S gem list | grep merb
merb (0.9.3)
merb-action-args (0.9.3)
merb-assets (0.9.3)
merb-builder (0.9.3)
merb-cache (0.9.3)
merb-core (0.9.3)
merb-freezer (0.9.3)
merb-gen (0.9.3)
merb-haml (0.9.3)
merb-mailer (0.9.3)
merb-more (0.9.3)
merb-parts (0.9.3)
merb_activerecord (0.9.3)

I installed merb from as a regular gem:
$ jruby -S gem install merb
$ jruby -S gem install activerecord-jdbcmysql-adapter

Please note that it’s only working with activerecord on jruby, as
datamapper
has C native extensions. Sequel seems to have beta jruby support, but I
haven’t tried.

$ jruby -S merb-gen app merbtest
RubiGen::Scripts::Generate
…
$ cd merbtest
$ jruby -S merb

I’m running it without any problems (http://localhost:4000). I could
also
generate scaffolds, after updating config/init.rb and
config/database.yml to
use activerecord and jdbcmysql-adapter.

$ jruby -S merb-gen resource post content:text author:string

BTW, …

$ jruby -S gem install jetty-rails
$ jruby -S jetty_merb

… works as well! :wink:
