java - Elastic Search Lucene version error

Question

I have a very simple ES Client which will send a query to local ES server(1.4.1 version of ES) and get the results and display to the user. Now, I took this code to a different project X and tried to use it along with X because I need some APIs from X. Now, when I run the same code when i am in X, then I get this error and don't know how to resolve. Can you please help me with this. Exception in thread "main" java.lang.NoSuchFieldError: LUCENE_3_6

Answer 1

It seems that you are trying to use Elasticsearch and Lucene in your project as separate libraries.

Elastissearch 1.4.1 is based on Lucene 4.10.2. You can check the release blog page here for more details.

To solve your problem you will need to update your Lucene library version to 4.10 and use Version.LUCENE_CURRENT instead of LUCENE_3_6.

You can find here Lucene 4.10 Core API documentation.

I hope that this will help. Don't hesitate to comment if you have doubts.
