Apache Camel Integration with Elasticsearch - elasticsearch

Question

I'm working on a project using Apache Camel and Elasticsearch and I was wondering which version of Elasticsearch does Camel support?
My pom.xml looks like this:
<dependencies>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-core</artifactId>
<version>2.18.2</version>
</dependency>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-elasticsearch</artifactId>
<version>2.18.2</version>
</dependency>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-xmljson</artifactId>
<version>2.18.2</version>
</dependency>
<dependency>
<groupId>xom</groupId>
<artifactId>xom</artifactId>
<version>1.2.5</version>
</dependency>
But when I want to route a file to elasticsearch, I've got the following error:
java.lang.IllegalStateException: Received message from unsupported version: [2.0.0] minimal compatible version is: [5.0.0]
I found that this exception is due to a node or a TransportClient using an old version. So I try to add the elasticsearch dependency :
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>5.1.2</version>
</dependency>
But it gives me a new error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/elasticsearch/action/WriteConsistencyLevel
So I'm wondering.. Which version of ES can I use with Apache Camel?
The code for trying to send data to elasticsearch:
XmlJsonDataFormat xmlJsonFormat = new XmlJsonDataFormat();
from("file://C:/Projects/?fileName=data.xml&charset=utf-8")
.marshal(xmlJsonFormat)
.to("elasticsearch://clusterES?transportAddresses=127.0.0.1:9300&operation=BULK_INDEX&indexName=xml&indexType=account");

I don't think you need to add any other pom except the camel-elasticsearch. It seems more likely that you have a TransportClient running on an older version. You need to find it and upgrade the TransportClient.
