nullpointer exception

[shenroong]

I used the exactly same example code from java redis example. I use maven to compile and package.

    final RedisClient client = RedisClient.create(vertx,
        new RedisOptions().setHost("127.0.0.1"));
java.lang.NullPointerException

I solved it. Redis.create should be inside start()
