NoClassDefFoundError exception with SearchSourceBuilder (6.0) in GWT server side

Elastic Stack Elasticsearch
1

Hi!

I try to query my local elastic search instance via high level rest client with:
SearchRequest searchRequest = new SearchRequest("jobs");
searchRequest.types("job");
SearchSourceBuilder ssb = new SearchSourceBuilder();
ssb.query(QueryBuilders.matchAllQuery());
searchRequest.source(ssb);

But searchRequest throws a NoSuchFieldError due to another exception in SearchSourceBuilder (NoClassDefFoundError).
I tried elastic version 6.0 and 5.6.4.

The code sample above is called on the server side of my gwt application.
I cleared my maven repo, reimport,... but no success.
Any ideas please?

What is the full error / stacktrace?

3

Method threw 'java.lang.NoClassDefFoundError' exception. Cannot evaluate org.elasticsearch.search.builder.SearchSourceBuilder.toString()
This is thrown when the default constructor in SearchSourceBuilder is called in the constructor for SearchRequest(String... indices) (SearchRequest:60)

There is no clear stacktrace, it's only visible that the field source in SearchRequest contains the message above (bold).
When I execute the request gwt catches an InvocatoinTargetException with the cause:
java.lang.NoClassDefFoundError: Could not initialize class org.elasticsearch.common.xcontent.json.JsonXContent
I guess this is just the resulting error from the corrupt request.

How did you import the High Level Rest Client in your project?

5

via maven:

org.elasticsearch.client
elasticsearch-rest-high-level-client
6.0.0

That's the only elasticsearch dependency in my pom.
I'll try an isolated version because I think it is maybe a clash with another dependency in the pom:

Could you try with only elasticsearch dependency so it will tell us if this is caused by a conflict or something else?

Ok, I got it up and running. I had a dependency on ektorp for my couchdb, because I wanted to port all couchdb entries into elastic. After removing all ektorp couchdb and lucene dependencies it worked perfectly. Thanks!
