I’ve written a custom task named update\_fbml.rake as follows:  
namespace :remote do  
task :update\_fbml =\> :environment do  
require “application”  
controller = ApplicationController.new  
controller.mass\_update\_fbml  
# `script/runner "require #{RAILS_ROOT}/app/controllers/application; ApplicationController.do_stuff"`  
end  
end

This executes on my local machine but when I deploy to my build server  
and type ‘rake remote:update\_fbml’ it fails with “Don’t know how to  
build task ‘remote:update\_fbml’”.

Any suggestions?

Make sure all your ‘require’ directives actually exist on the build  
server.

If one of the .rake files can’t load a required file (e.g. a gem)  
then it won’t actually get parsed properly by rake but you won’t see  
a failure message either. It just gets quietly dumped.
