Add hook for deploy failure If an error is raised during a deploy, the task `deploy:failed` will be triggered. Custom tasks can hook into this using `after`: after 'deploy:failed', :send_for_help do # end I've also taken the opportunity to provide a marginally more useful error message before triggering the task. By default, this 'deploy:failed' will only be triggered when running `cap <stage> deploy` - to trigger after individual tasks use `set :deploying, true` This closes #708 and replaces https://github.com/capistrano/capistrano/pull/720 2013-11-01 11:59:13 +00:00			`set :fail, proc { fail }`
