Sinatra Jruby Heroku - jruby: No such file or directory -- trinidad (LoadError)

Question

I'm trying to get this application running: github.com/Soliah/sinatra-jruby-heroku.git

One update was necessary according to this release note from Heroku:

http://devcenter.heroku.com/articles/release-note-java-2011-09-29

The build goes fine, without any errors. Bellow some log parts:

   [INFO] --- jruby-rake-plugin:1.6.3:jruby (install-bundler) @ jruby-heroku ---

But when I access the deployed application. An application error occurs.

Here is the log, with the error:

It seems that JRuby is not finding the gems. But I've tried all kinds of configurations (in script/jruby, heroku config:add, Procfile, etc.) and no one worked.

One more thing: this is the actual heroku config output (stack cedar).

  $ heroku config
  DATABASE_URL        => postgres://kfgubrhars:[email protected]/kfgubrhars
  JAVA_OPTS           => -Xmx384m -Xss512k -XX:+UseCompressedOops
  MAVEN_OPTS          => -Xmx384m -Xss512k -XX:+UseCompressedOops
  PATH                => /usr/local/bin:/usr/bin:/bin
  SHARED_DATABASE_URL => postgres://kfgubrhars:[email protected]/kfgubrhars

Here is the updated repository: https://github.com/tomasmuller/sinatra-jruby-heroku

Thank's in advance!

Ok! I found the solution. Here are the steps:

• Adjust the GEM_HOME, in script/jruby to:

  GEM_HOME="$APPDIR"/vendor/bundle
  

• Created the script/bundle, with ENV['GEM_HOME'] and ENV['GEM_PATH'] pointing to 'vendor/bundle' dir.

• Adjusted the executions of jruby-rake-plugin, in pom.xml:

  install-bundler: <args>-S gem install bundler --no-ri --no-rdoc --install-dir vendor/bundle</args>
  
  bundle-install: <args>script/bundle install --without development:test</args>
