How can I set the rcov task if the subtask fails?

I have this task:

task :all => ['foo', 'bar', 'announce_success']

If foothey bardo not create exceptions, then it announce_successhappens. How can I perform a specific task or block of code if they make exceptions?

The way you defined your tasks will cause rake to exit as soon as one of the dependencies completes with an error / calls and exception. This is the main functionality of the rake.

One way around this is to do something like

task :all do
 task :tmp => ['foo','bar']
 begin 
   Rake::Task[:tmp].invoke
 rescue
  #do something with the exception
 end
end

Unfortunately, this goes against the grain of rake.

Ruby at_exit, , , Rake . rake-tasks at_exit hook :

  task :cleanup do
    at_exit {
      # cleanup code here
    }
  end

, :cleanup .
