capistrano3 でデプロイ時のSkipping task `puma:restart'.の解決方法がわからないので教えていただけないでしょうか？

Railsアプリケーションをcapistrano3でデプロイしたいのですが、
$ bundle exec cap production deploy --trace --dry-run を実行すると以下のような表示が出てきます。これってなんでしょうか？エラーなのでしょうか？

Skipping task `puma:restart'.
Capistrano tasks may only be invoked once. Since task `puma:restart' was previously invoked, invoke("puma:restart") at /home/vagrant/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/capistrano3-puma-3.1.1/lib/capistrano/tasks/puma.rake:96 will be skipped.
If you really meant to run this task again, use invoke!("puma:restart")
THIS BEHAVIOR MAY CHANGE IN A FUTURE VERSION OF CAPISTRANO. Please join the conversation here if this affects you.
