I am just starting to learn to use elasticsearch and trying to get some documents from elasticsearch server using java rest client in the first picture.

An error occured when I ran the code as an application.Here is the error information

I checked out the source of org.elasticsearch.Version.jave in elasticsearch-7.0.0-beta1.jar and found  
public static final Version V\_7\_0\_0 = new Version(V\_7\_0\_0\_ID, org.apache.lucene.util.Version.LUCENE\_8\_0\_0);  
at line 126.  
Then I looked up into org.apache.lucene.util.Version.java which I downloaded from [http://lucene.apache.org/core/](http://lucene.apache.org/core/) and found no LUCENE\_8\_0\_0 in it because the latest LUCENE version is 7.7.0

I asked this question on GitHub([https://github.com/elastic/elasticsearch/issues/39387](https://github.com/elastic/elasticsearch/issues/39387)) and got a reply said there is a snapshot of LUCENE 8.0 in elasticsearch-7.0.0-beta1.jar.So, I checked other folders in elasticsearch-7.0.0-beta1.jar and there is no org/apache/lucene/util folder in it.I also checked elasticsearch-7.0.0-alpha2.jar and found nothing.

I am wondering if anyone can help me solve this problem.

The NoSuchField error most likely indicates a problem in your project dependencies. Which version of the Java Rest Client are you using exactly? Did you also add a dependency to Elasticsearch in a specific version?

Cheers

Did you add the Lucene snapshot repository as the documentation says? See [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.0/java-rest-high-getting-started-maven.html#java-rest-high-getting-started-maven-lucene](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.0/java-rest-high-getting-started-maven.html#java-rest-high-getting-started-maven-lucene)
