I am upgrading from 6.1.3 to 6.3.0

I am trying to initialize:  
SearchSourceBuilder ssb = new SearchSourceBuilder();

Getting this error on above line:

```
java.lang.NoSuchFieldError: LUCENE_7_3_1
	at org.elasticsearch.Version.<clinit>(Version.java:168)

```

This worked well with 6.1.3.

My bad. I had got 7.2.1 dependency on my classpath. Fixed it myself.
