    end
  end
  nil
rescue Rake::RuleRecursionOverflowError => ex
  ex.add_target(task_name)
  fail ex
end

If a rule can be found that matches the task name, enhance the task with the prerequisites and actions from the rule. Set the source attribute of the task appropriately for the rule. Return the enhanced task or nil of no rule was found.

  message = "Don't know how to build task '#{task_name}' "\

  name ||= generate_name
  @scope = Scope.new(name, @scope)

lookup (task_name, initial_scope=nil)

# File vendor/bundle/ruby/3.4.0/gems/rake-13.2.1/lib/rake/task_manager.rb, line 192
def lookup(task_name, initial_scope=nil)
  initial_scope ||= @scope

    task_name = task_name.sub(/^rake:/, "")
  elsif task_name =~ /^(\^+)/

    task_name = task_name.sub(/^(\^+)/, "")
  else
    scopes = initial_scope
  end
  lookup_in_scope(task_name, scopes)
end

Lookup a task, using scope and the scope hints in the task name. This method performs straight lookups without trying to synthesize file tasks or rules. Special scope names (e.g. ‘^’) are recognized. If no scope argument is supplied, use the current scope. Return nil if the task cannot be found.

  end
end

Resolve the arguments for a task/rule. Returns a tuple of [task_name, arg_name_list, prerequisites, order_only_prerequisites].
