Hi guys,
I need a little help with new elasticsearch
i made a small client for testing
@Singleton
@Startup
public class NativeElasticSingleton {
```
private TransportClient client;
@PostConstruct
private void init() {
try {
client = new PreBuiltTransportClient(Settings.EMPTY)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host1"), 9300))
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host2"), 9300));
} catch (UnknownHostException e) {
}
}
```
i debug a little and it try to add the native plugins
Arrays.asList(
Netty3Plugin.class,
Netty4Plugin.class,
ReindexPlugin.class,
PercolatorPlugin.class,
MustachePlugin.class));
and i'm getting
Caused by: java.lang.NoSuchMethodError: org.elasticsearch.transport.client.PreBuiltTransportClient.addPlugins(Ljava/util/Collection;Ljava/util/Collection;)Ljava/util/Collection;
at org.elasticsearch.transport.client.PreBuiltTransportClient.(PreBuiltTransportClient.java:69)

Hi @Andre_Fedorenko,
`java.lang.NoSuchMethodError` when a method was present at compile time but was not found at runtime. It sounds to me that you tried to call the method in an IDE debug window. Did you notice that the method `addPlugins` is declared as `protected`? You are supposed to add plugins only in the constructor of `PreBuiltTransportClient`. You can see an [example in our client benchmarks](https://github.com/elastic/elasticsearch/blob/194a6b1df031a95977b6ca395a74a8b74d9af31d/client/benchmark/src/main/java/org/elasticsearch/client/benchmark/transport/TransportClientBenchmark.java#L52-L56).
