How to reference a function in a different rake file

Question

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.

Answer 1

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
