Question

I have this task:

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

If foo and bar don’t raise exceptions, then announce_success happens. How can I have a particular task or code block execute if they do raise exceptions?

Answer 1

The way you have defined your tasks will cause rake to exit as soon as one of the dependencies fails/raises and exception. This is the core functionality of rake.

One way to work around though 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
