Stop Capistrano default tasks for non-rails apps

I was getting errors when using I was using capistrano to deploy a non-rails app:

*** [err :: 192.168.33.22] find:
*** [err :: 192.168.33.22] `/home/petems/fakerepo/releases/20130227170824/public/images'

I forgot that Capistrano runs some tasks by default when you do a deploy

So a quick fix to change that:

# Override default tasks which are not relevant to a non-rails app.
namespace :deploy do
  task :migrate do
    puts "    Not doing migrate because we are not a Rails application."
  end
  task :finalize_update do
    puts "    Not doing finalize_update because we are not a Rails application."
  end
  task :start do ; end
  task :stop do ; end
  task :restart do ; end
end

And viola!

 ** [out :: 192.168.33.22]

Not doing finalize_update because we are not a Rails application.

If you want a more elegant solution, I've heard some good things about railsless-deploy, a dedicated gem for deploying non-rails apps with Capistrano.
