Custom Rake task unable to be called twice in same Rakefile unike Rake::TestTask - ruby

Question

I recently read an "older", 2009, article about how to make a Custom Rake tasks. So far it works for the first iteration, but I saw that Rake::TestTask can be called twice, so I figured I could do it, however my name attr_accessor is not picking up the symbol I'm passing to it.
require 'rake'
require 'rake/tasklib'
module Phil
class FooTask < Rake::TaskLib
attr_accessor :name
attr_accessor :data
attr_accessor :task_dependencies
def initialize(name = :task, task_dependencies)
#name = name
#data = nil
yield self if block_given?
#task_dependencies = task_dependencies
define
end
def define
desc "Run the #{#name} task"
task #name => #task_dependencies do
puts 'Some Test being Printed'
puts #data
sh 'echo blah'
end
self
end
end
end
Phil::FooTask.new :foo, [:call_me_first, :call_me_second]
task :call_me_first do
puts 'I am called first because I am a dependency'
end
task :call_me_second do
puts 'I am called second because Im also a dependency'
end
Phil::FooTask.new(:stuff) do |t|
t.data = 'I am a stuff task.'
end
The following is the results I get.
C:\Users\user01\Desktop
λ rake --tasks
rake foo # Run the foo task
rake stuff # Run the stuff task
C:\Users\user01\Desktop
λ rake foo
I am called first because I am a dependency
I am called second because Im also a dependency
Some Test being Printed
echo blah
blah
C:\Users\user01\Desktop
λ rake stuff --trace
** Invoke stuff (first_time)
rake aborted!
Don't know how to build task '{}' (see --tasks)

Tasks: TOP => stuff
I'm not sure why the Rake task is failing. Even from reading the Rake's TestTask code, it seems I'm doing mostly everything correctly. I'll also say that I'm not a professional on Ruby and all the little tricks.

Keep arguments with default value at the end in method declaration!
The reason rake stuff is raising error is because of your Phil::FooTask.new(:stuff) do |t| call. Your initialize method expects two arguments. The error is in your declaration of the constructor where you've declared name = :task which has a default value of :task. However, the second parameter task_dependencies is expected. It is the second parameter that you're missing when initializing task with name :stuff.
Modify your initialize method declaration as follows:
def initialize(name = :task, task_dependencies = [])
Then you should see correct tasks when invoking rake -T:
rake foo # Run the foo task
rake stuff # Run the stuff task
