module Capistrano
# This module extends a Rake::Task to freeze it to prevent it from being
# enhanced. This is used to prevent users from enhancing a task at the wrong
# point of Capistrano's boot process, which can happen if a Capistrano plugin
# is loaded in deploy.rb by mistake (instead of in the Capfile).
#
# Usage:
#
# task = Rake.application["load:defaults"]
# task.invoke
# task.extend(Capistrano::ImmutableTask) # prevent further modifications
#
module ImmutableTask
def self.extended(task)
task.freeze

$stderr.puts <<-MESSAGE
ERROR: #{name} has already been invoked and can no longer be modified.
Check that you haven't loaded a Capistrano plugin in deploy.rb or a stage
(e.g. deploy/production.rb) by mistake.
Plugins must be loaded in the Capfile to initialize properly.
MESSAGE
# This will raise a frozen object error
