If the required plugin is not bundled by default, you can install it using the binlogstash-plugin install command. For example, to install the logstash-output-email plugin, execute the following command:
E:logstash-7.0.0in>logstash-plugin install logstash-output-email
By using the binlogstash-plugin update command and passing the plugin name as a parameter to the command, you can get the latest version of the plugin:
E:logstash-oss-7.0.0in>logstash-plugin update logstash-output-s3
Executing just the binlogstash-plugin update command would update all the plugins.
