A more powerful and stable Java client library for the awesome etcd, a highly available key value store. This library is based on Apache HttpAsyncClient, provides async api. It supports all key based etcd requests, adds request redirect handler and retry handler, which is really useful when you put etcd into production cluster.This library has been used in real production for period of time.

<version>1.2</version>
</dependency>
compile 'com.xqbase:etcd4j:1.2'
Check out the EtcdClientTest.java for more details about how to use this library, but here's a quick code example:
EtcdClient client = new EtcdClient(URI.create("http://127.0.0.1:4001"));
String key = "/message";
// set the key
client.set(key, "beepboop");
// get the value of the key
String value = client.get(key);
Assert.assertEquals("beepboop", value);
// delete the key
client.delete(key);
value = client.get(key);
Assert.assertNull(value);
