rails: debug rails application in eclipse / aptana

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"
gem "libv8" ,'3.16.14.3'

gem 'twitter-bootstrap-rails', "=2.2.6"

gem 'rspec-rails'
# To use ActiveModel has_secure_password

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
