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](http://central.maven.org/maven2/org/elasticsearch/elasticsearch/2.1.1/elasticsearch-2.1.1.pom) is "test". I think that means that the remaining dependencies get the default scope of 'compile'.

I realize this hasn't happened yet...

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.
