Hi, I am using elasitcsearch 7.4.2 with openjdk 11. I can't change all the api to REST, I will do little by little. All CURD I have change to REST (working good) but only for search I want to use TransportClient.

The below is my code which return me the Client  
private void transportClient(int esPort, String host, String cluster) {  
try {  
Settings settings = Settings.builder().put("cluster.name", cluster).put("client.transport.ignore\_cluster\_name",true).build();  
TransportClient transportClient = new PreBuiltTransportClient(settings);  
Client esClient = transportClient.addTransportAddress(new TransportAddress(InetAddress.getByName(host), esPort));  
} catch (Exception e) {  
}  
}  
But I am getting the following exception. But when I use pom.xml I not facing any issue. When I use without pom.xml (but I have downloaded all the required jars) I am facing the following error.  
Kindly help me on this

Hi @rajesh_elasticsearch,

`GenericAction` was removed in 7.0. You must have something referring to it still on your classpath, could be a plugin or some other dependency.

The following are the plugin which pointing to the old version. At the time of new PreBuiltTransportClient , this are the plugin loading and in my case its point to the old jar.  
I have removed the old plugin jars and now its working fine.

org.elasticsearch.transport.Netty4Plugin,  
org.elasticsearch.index.reindex.ReindexPlugin,  
org.elasticsearch.percolator.PercolatorPlugin,  
org.elasticsearch.script.mustache.MustachePlugin,  
org.elasticsearch.join.ParentJoinPlugin

Thanks you HenningAndersen.
