This document do not show the prerequisite to make a custom java plugin.  
I am using logstash 6.5.4  
is it available to make a custom one?  
Also, is there a logstash codebase jar available directly instead of ./gradlew assemble because i do not have network access for my server  
It is really frustrating.  
Thank you in advance
