How to reference a function in a different rake file

I want to call a function that is in another rake file.

Rake File 1:

task :build => [:some_other_tasks] do
  foo
end

def foo(type = :debug)
  # ...
end

Rake File 2:

require_relative 'path_to_rake_file_1' 

task :foo2 => [:some_other_tasks] do
      foo
    end
    

I am currently getting a no such file to load error despite confirming the path is absolutely correct.

Instead of defining methods inside rake files and sharing them among rake tasks, it is best practice to create a RakeHelper module and include it in your rake file. So, you could have something like:

rake_helper.rb

module RakeHelper
  def self.foo
  end
end

task1.rake

include RakeHelper

task :build => [:some_other_tasks] do
  RakeHelper.foo
end

task2.rake

include RakeHelper

task :foo2 => [:some_other_tasks] do
  RakeHelper.foo
end
