In [official doc](https://www.elastic.co/guide/en/watcher/2.0.0-rc1/api-java.html) of watcher, it claims one should add this maven dependency to `pom.xml` to use watcher plugin:

```
     <dependency>
         <groupId>org.elasticsearch.plugin</groupId>
         <artifactId>elasticsearch-watcher</artifactId>
         <version>2.0.0-rc1</version>
      </dependency>

```

But when I doing this so, `mvn clean install` gives:

```
 Could not transfer artifact org.elasticsearch.plugin:elasticsearch-watcher:pom:2.0.0-rc1 from/to elasticsearch-releases (http://maven.elasticsearch.org/releases): Not authorized

```

Whole message:

> Failed to execute goal on project crawler-elasticsearch: Could not resolve dependencies for project com.enniu.cloud.services:crawler-elasticsearch:jar:1.2-SNAPSHOT: Failed to collect dependencies at org.elasticsearch.plugin:elasticsearch-watcher:jar:2.0.0-rc1: Failed to read artifact descriptor for org.elasticsearch.plugin:elasticsearch-watcher:jar:2.0.0-rc1: Could not transfer artifact org.elasticsearch.plugin:elasticsearch-watcher:pom:2.0.0-rc1 from/to elasticsearch-releases ([http://maven.elasticsearch.org/releases](http://maven.elasticsearch.org/releases)): Not authorized , ReasonPhrase:Unauthorized. -\> [Help 1]

By the way, we trying to use watcher `2.0.0-rc1` because now we have upgraded our elasticsearch to `2.0.0-rc1 `.

If we can't use `2.0.0-rc1` of watcher, which version should we use with elasticsearch `2.0.0-rc1`?

Hey,

can you try this and tell me if it works? Looks as if the docs are wrong, but I want to be sure first:

It works. BTW, @warkolm told me watcher 2.0.0-rc1 not available now in elasticsearch IRC.

Hey,

this looks as if the client you are using does not load the watcher plugin. Can you show code, where you instantiate the client that you wrap around `WatcherClient`

```java
        Settings settings = Settings.builder().put("plugin.types", WatcherPlugin.class.getName()).build();

        TransportClient client = TransportClient.builder().settings(settings).build();
        client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
        WatcherClient watcherClient = new WatcherClient(client);

```

in addition you can try the above snippet and see if it works.

The code to instantiate the `WathcerClient`:

```
    client = TransportClient.builder().settings(
            Settings.settingsBuilder().put("cluster.name", "elasticsearch_dc_001").build()
    ).build()
            .addTransportAddress(
                    new InetSocketTransportAddress(
                            InetAddress.getByName("x.x.x.x"), 9300
                    )
            );
    WatcherClient watcherClient = new WatcherClient(client);
```

That works! But I think it would be better if that code appears in watcher 2.0.0 official docs.
