rails: debug rails application in eclipse / aptana - ruby-on-rails

Question

I can debug one of my old application. But when I create a new application. I tried to debug using eclipse / aptana. THe debugger didn't launch at all.
Gemfile for my old application
source 'http://rubygems.org'
gem 'rails', '4.0.0'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails'
gem 'coffee-rails'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'protected_attributes'
gem 'jquery-rails'
gem 'devise'
gem "less-rails"

Thanks for this post
Rails 4.0 project not starting through aptana studio 3
Create a folder script in the root of the app and place rails file from the bin folder to the script folder then it will work. You might need to change the web-server options in the aptana setting also.
I was having the same problem but this fix fixed it
