Is the version of elasticsearch version of Guice different from 3.0? Same question for the other libs that are in elasticsearch. Now that elasticsearch supports Maven, would it make sense not to bundle code that is unchanged in elasticsearch? ---

Having theses libs embedded in ES lets developpers use their own version of useful libs without classloading issues.

It would, but only for people running elasticsearch in an OSG environment. You wouldn't want to be forced to use the same version of the libraries that elasticsearch happens to use... ---

elasticsearch uses guice 2.0, and its a modified version than the one provided (mainly to reduce its memory footprint). Once, before even using Guice 2.0 embedded codebase, we upgraded to 3.0 and it used even more memory and was considerable slower. As far as Guice is concerned, its now part of elasticsearch and is considered internal (but can be used by plugins).
