How do I invoke one Capistrano task from another?

For example:

task :foo do
  # stuff
end

task :bar do
  # INVOKE :foo
end

回答1:

You can do it by using namespace:

namespace :test do
  task :one do
  end
  task :two do
    test.one
    #or just directly call it:
    one
  end
end

Just be careful with the name you use to not overwrite some important function.

回答2:

For the record: in the Capistrano 3, use invoke(), e.g.

desc "Task that does something"
task :do_something do
  invoke 'namespace:task'
end

回答3:

Generally you do this by defining dependencies:

before :bar, :foo

回答4:

you also could use Rake::Task["namespace:task"].invoke, this works

回答5:

If the task lives in another namespace, you can use find_and_execute_task instead.
