Offline plugin installation problem

[mevbas (Muharrem Evbaş)]

Hi,
I created logstash-offline-plugins zip file for email output plugin with Logstash 5.3.0

Zip file contains
-logstash folder
--dependencies
---mail-2.6.4.gem
---mime-types-2.6.2.gem
--logstash-output-email-4.0.3.gem

When I try to install it offline server, I'm getting this error message
"Could not find gem 'logstash-output-email (= 4.0.3) java' in any of the gem sources listed in your Gemfile or installed on this machine."

Hello @mevbas, did you use the prepare-offline-pack subcommand to generate the zip?

Using Logstash 5.3.0, I was able to do the following:

• install the logstash-output-email
• bin/logstash-plugin prepare-offline-pack logstash-output-email
• turn off internet
• bin/logstash-plugin install file:///tmp/logstash-offline-plugins-5.3.0.zip
