I am using elasticsearch 6.1.1 alongside spring and I am getting the following error
NoSuchMethodError: org.elasticsearch.common.xcontent.XContentBuilder.string()Ljava/lang/String what might be the reason?
When using springboot with
elasticsearch, you need to be explicit with some transitive dependencies as SpringBoot declares a version 6.4...
Basically you can put this in your pom.xml:
<properties>
<elasticsearch.version>7.0.0<elasticsearch.version>
</properties>
See documentation here: https://docs.spring.io/spring-boot/docs/current/reference/html/howto-build.html#howto-customize-dependency-versions
Thanks. Actually, I am using gradle which manages the dependencies. I added these to lines to build.gradle, which seems to solve the problem.
compile 'org.elasticsearch:elasticsearch:6.1.1'
compile group: 'org.elasticsearch.client', name: 'transport', version: '6.1.1'Yet, there is another issue. It says that spring cannot instantiate a bean which is caused by:
Caused by: java.lang.NoSuchMethodError: org.elasticsearch.search.fetch.subphase.highlight.HighlightPhase.<init>(Ljava/util/Map;)V
I think spring tries to invoke the constructor of the HighlightPhase class, which is supposed to have a no-arg constructor. However, such a constructor does not exist. What can I do to resolve this issue?
Try a more recent version like 6.8.
I tried that but another error occurred 
java.lang.NoSuchMethodError: org.elasticsearch.plugins.ActionPlugin$ActionHandler.<init>(Lorg/elasticsearch/action/Action;Ljava/lang/Class;[Ljava/lang/Class;)V
May be switch to the Rest client ?
I do not understand what you mean by switching to Rest client. could you be more specific about what changes are needed?
I mean: don't use the TransportClient anymore but the Rest Client.
