How do I execute Rake tasks with arguments multiple times?

Question

It\'s not possible to invoke the same rake task from within a loop more than once. But, I want to be able to call rake first and loop through an array

Answer 1

You can use Rake::Task#reenable to allow it to be invoked again.

desc "first task"
task :first do 
  other_arg = "bar"
  [1,2,3,4].each_with_index do |n,i|
    if i == 0 
      Rake::Task["second"].invoke(n,other_arg)
    else
      # this does work
      Rake::Task["second"].reenable
      Rake::Task["second"].invoke(n,other_arg)
    end
  end
end

task :second, [:first_arg, :second_arg]  do |t,args|
  puts args[:first_arg]
  puts args[:second_arg]
  # ...
end

$ rake first

1
bar
2
bar
3
bar
4
bar
