如何从 Rake 任务中运行 Rake 任务？ - How to run Rake tasks from within Rake tasks?

问题：

I have a Rakefile that compiles the project in two ways, according to the global variable $build_type , which can be :debug or :release (the results go in separate directories):我有一个 Rakefile，它根据全局变量$build_type以两种方式编译项目，它可以是:debug或:release （结果在单独的目录中）：

task :build => [:some_other_tasks] do
end

I wish to create a task that compiles the project with both configurations in turn, something like this:我希望创建一个任务，依次使用两种配置编译项目，如下所示：

task :build_all do
  [ :debug, :release ].each do |t|
    $build_type = t
    # call task :build with all the tasks it depends on (?)
  end
end

Is there a way to call a task as if it were a method?有没有办法像调用方法一样调用任务？ Or how can I achieve anything similar?或者我怎样才能实现类似的目标？
