如何在所有其他任务之后运行 Rake 任务?(即 Rake AfterBuild 任务) [英] How do I make a Rake Task run after all other tasks? (i.e. a Rake AfterBuild task)

问题描述

我是 Rake 的新手，我用它来构建 .net 项目.我感兴趣的是有一个总结任务，它打印出已经完成的事情的总结.我希望这个任务总是被调用，无论 rake 是用什么任务调用的.

I'm new to Rake and using it to build .net projects. What I'm interested in is having a Summary task that prints out a summary of what has been done. I want this task to always be called, no matter what tasks rake was invoked with.

有没有一种简单的方法可以做到这一点?

Is there an easy way to accomplish this?

谢谢

更新问题，回复Patrick 的回答 我想要的是在所有其他任务之后运行一次的后任务，所以我想要的输出是:

Update on the question, responding to Patrick's answer what I want is the after task to run once after all other tasks, so the output I want is:

task :test1 do 
  puts 'test1'
end

task :test2 do 
  puts 'test2'
end

Rake::Task.tasks.each do |t|
    <Insert rake magic here>
#  t.enhance do 
#    puts 'after'
#  end
end

$ rake test1
test1
after

$rake test2
test2
after

$rake test1 test2  
test1
test2
after

如果

task :test3 =>[:test1, :test2]
   puts 'test3'
end

    $rake test3
test1
test2
test3
after

Even though the bounty is gone, any further help much appreciated. (Sadily I don't think that I can offer another bounty.)

推荐答案

将此作为新答案发布以保持另一个可用.这不太优雅，因为我必须深入了解 Rake 并手动更新任务列表，但它确实有效.

Posting this as a new answer to keep the other one available. This is much less elegant as I have to get into the guts of Rake and manually update the task list, but it works.

task :test1 do
  puts 'test1'
end

task :test2 do 
  puts 'test2'
end

task :after do
  puts 'after'
end

# top_level_tasks is't writable so we need to do this ugly
# instance_variable_set hack...
current_tasks =  Rake.application.top_level_tasks
current_tasks << :after
Rake.application.instance_variable_set(:@top_level_tasks, current_tasks)

输出:

$ rake test1
test1
after

$ rake test1 test2
test1
test2
after
