Hello, I need to use [logstash-output-jdbc](https://github.com/theangryangel/logstash-output-jdbc) with some modification, so I've done the following steps: I've cloned logstash-output-jdbc plugin. I've done changes to the code in `jdbc.rb` and built a gem using: `gem build logstash-output-jdbc.gemspec` Now I tried to install it to logstash using: `./logstash-plugin install logstash-output-jdbc-5.3.0-java.gem` (I was in the bin directory of logstash and put the gem there) Got the following output: `Validating logstash-output-jdbc-5.3.0-java.gem` `Installing logstash-output-jdbc` `Installation successful` Now I ran: `./logstash-plugin list | grep jdbc` And the output is: `logstash-filter-jdbc_static` `logstash-filter-jdbc_streaming` `logstash-input-jdbc` No sign for logstash-output-jdbc. What's might be going wrong? Thanks in advance! ---
