Java client with minimal dependencies

Elastic Stack Elasticsearch
1

I'm using Ivy for dependency management (yep, I'm the one) instead of Maven. I just want to see if I can trim my dependencies at all for a simple Node Client?

Namely the whole Ivy config to Maven scope thing is a bit confusing. From what I can see the only scope defined in the pom is "test". I think that means that the remaining dependencies get the default scope of 'compile'.

I realize this hasn't happened yet...

and possibly even creating a thin Java client for Elasticsearch with minimal dependencies

Thought it couldn't hurt to ask, in case I missed a post or other document, maybe mentioning certain dependencies that could be excluded?

I think you need almost everything for the Node Client.

For a TransportClient you might need less deps such as guava or joda but I never tested that so I'm unsure.
