NoClassDefFoundError HttpAsyncResponseConsumer

getting following error
java.lang.NoClassDefFoundError: org/apache/http/nio/protocol/HttpAsyncResponseConsumer
for code-
RestClientImpl impl=new RestClientImpl();
impl.restClient= RestClient.builder( new HttpHost("localhost", 9200)).build();

imported these two-
import org.apache.http.HttpHost;
import org.apache.http.impl.nio.client.HttpAsyncClientBuilder;

using ES v5 rest api jar.

I believe this is the same problem as

You can work around it by adding the http client's dependencies to your POM. In gradle they look like:

  compile "org.apache.httpcomponents:httpclient:4.5.2"
  compile "org.apache.httpcomponents:httpcore:4.4.5"
  compile "org.apache.httpcomponents:httpasyncclient:4.1.2"
  compile "org.apache.httpcomponents:httpcore-nio:4.4.5"
  compile "commons-codec:commons-codec:1.10"
  compile "commons-logging:commons-logging:1.1.3"

I won't try to translate that to maven because I can't test it locally at this point but it should be fairly trivial. I'll update the issue I linked above to make it clear that this is also happening for the http client.

Actually the pom looks right to me. How are you attempting to resolve the transitive dependencies?

resolved it. There was some issue with my eclipse.
