HI,
the problem you are encountering here is with the dependencies of the plugin, you actually need them to have the plugin installed and the `.gem` files hasn't them. For now, and until we have [https://github.com/elastic/logstash/pull/3404](https://github.com/elastic/logstash/pull/3404) merged, the easiest path for you will be to install the plugin in a machine with internet, including the dependencies and then move this to your offline environment.
Does this help your for now?

Thank you for your answer.
I understand that logstash-input-jdbc should be installed in a machine with Internet.
I read [https://github.com/elastic/logstash/pull/3404](https://github.com/elastic/logstash/pull/3404) ,but I don't understand these contents.
I guess if I want to install plugins(logstash-input-jdbc) with offline,I should have skills of Ruby.
therefore, I am trying to learn Ruby.
Sincerely.
