How to run Rake tasks from within Rake tasks?

If you need the task to behave as a method, how about using an actual method?

task :build => [:some_other_tasks] do  buildendtask :build_all do  [:debug, :release].each { |t| build t }enddef build(type = :debug)  # ...end

If you'd rather stick to rake's idioms, here are your possibilities, compiled from past answers:

• This always executes the task, but it doesn't execute its dependencies:

  Rake::Task["build"].execute

• This one executes the dependencies, but it only executes the task if it has not already been invoked:

  Rake::Task["build"].invoke

• This first resets the task's already_invoked state, allowing the task tothen be executed again, dependencies and all:

  Rake::Task["build"].reenableRake::Task["build"].invoke

• Note that dependencies already invoked are not automatically re-executed unless they are re-enabled. In Rake >= 10.3.2, you can use the following to re-enable those as well:

  Rake::Task["build"].all_prerequisite_tasks.each(&:reenable)

for example:

Rake::Task["db:migrate"].invoke

task :build_all do  [ :debug, :release ].each do |t|    $build_type = t    Rake::Task["build"].reenable    Rake::Task["build"].invoke  endend

That should sort you out, just needed the same thing myself.
