Hello, Is it possible to un jar-jar libraries, bundled with elasticsearch? Half of libraries that are there, already used in our application (jackson, digest, httpclient, netty, etc.) and it would be great to reduce permgen size. Thanks, Alexandr Vasilenko Web Developer ---

With the new build in master its possible to do it, though make sure that the versions are the same, as the ones elasticsearch uses include important bug fixes (out of the one you listed, elasticsearch uses jackson and netty).

Thanks for info, Shay. I'm very new to maven, can you tell me what arguments to mvn should I use?

You'll need to clone the repo yourself, and remove some dependencies from the shade plugin in the pom.xml. I highly suggest against it though, its very important to use the latest versions of the libraries _and_ maintain it.
