Java elasticsearch client always null

Question

I've recently made the switch from elasticsearch 1.7 to 2.0 and I noticed the way you setup the client has changed. I went through the documentation and for some reason the client is always null. I was wondering if I have set it up correctly.

Here is my code:

    Client client = null;

    try {
        client = TransportClient.builder().build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
    } catch (Exception e) {
        Logger.log(e);
    } finally {
        client.close();
        try {
            conn.close();
        } catch (SQLException e) {
            Logger.log(e);
        }
    }

As noted in the comments, but a little bit more in detail: Elasticsearch 2.0 uses Guava 18.0 (see https://github.com/elastic/elasticsearch/pull/7593). So to fix errors like java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.directExecutor()Ljava/util/concu‌rrent/Executor;, make sure to use Guava 18.0 as dependency and not other versions.
