Running the Java client fine in version 5.3.0.
Now, I try to reproduce the Java API graph exploration example posted in April 2016:
This example uses TransportClient.builder().addPlugin(GraphPlugin.class), and this syntax is not available in the stable relase 5.3.0 of the Java API I believe.
Trying to update in maven to 5.3.1 SNAPSHOT, I get:
"The POM for org.elasticsearch:elasticsearch:jar:5.3.1-SNAPSHOT is missing, no dependency information available"
