Question

I have a project that consists of multiple projects, something like:

my_project\
proj_A\
(code, tests, Rakefile, etc)
proj_B\
(code, tests, Rakefile, etc)
proj_C\
(code, tests, Rakefile, etc)

I’d like to create a Rakefile under “my_project” that can execute the Rakefile’s in the other projects. For example to package up the entire app I need to run tasks defined in the Rakefile’s in proj_A, proj_B and then proj_C (in that order).

What’s the best way to do this? Just have a Rakefile that defines tasks which call out to the other Rakefiles?

Answer 1

Create a rake task that depends on all the other projects.

import 'projdir1/Rakefile'
import 'projdir2/Rakefile'

task :finalproject => [:project1, :project2] do
  # do nothing or maybe some cleanup
end

The tasks :project1 and :project2 would be defined in the external rakefiles being included.
