Where is logstash classpath in windows?

Question

I've spent hours with google trying to select data from a table of my postgres and insert it to elasticsearch (ES) by logstash in windows. Logstash didn't see driver class where I tried to determine jar by

jdbc_driver_library 

option

Answer 1

Next I removed that line and then I saw "enable to find this jar in logstash classpath" error. Where is It in windows?! The location is:

[disk]:[logstash_folder]\logstash-core\lib\jars

Logstash is trying to find them there, so we need to put jars to this folder. After that everything works right and correct.

ES/Logstash v6
