无法创建PreBuiltXPackTransportClient x-pack弹性搜索

Question

包装手表。我添加了x-pack的依赖。

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>x-pack-transport</artifactId>
    <version>5.3.3</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.7</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.7</version>
</dependency>

我可以使用curl请求创建观察者但无法从java代码创建。我使用curl创建了一个观察者并尝试从jave代码中获取它。这是我的代码。

package watcher;

import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.Map;

import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.xpack.XPackClient;
import org.elasticsearch.xpack.client.PreBuiltXPackTransportClient;
import org.elasticsearch.xpack.watcher.client.WatcherClient;
import org.elasticsearch.xpack.watcher.support.xcontent.XContentSource;
import org.elasticsearch.xpack.watcher.transport.actions.get.GetWatchResponse;

public class GetWatcher {

    public static void main(String[] args) throws UnknownHostException {

        @SuppressWarnings("resource")
        TransportClient client = new PreBuiltXPackTransportClient(
                Settings.builder().put("cluster.name", "my-application").build())
                        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

        XPackClient xpackClient = new XPackClient(client);
        WatcherClient watcherClient = xpackClient.watcher();

        GetWatchResponse getWatchResponse = watcherClient.prepareGetWatch("my-watch").get();
        XContentSource source = getWatchResponse.getSource();
        Map<String, Object> map = source.getAsMap();
        for (String key : map.keySet()) {
            System.out.println(key);
        }

    }
}

它给出了错误 -

我尝试过使用PreBuiltTransportClient客户端。我可以使用此客户端获取elasticsearch的所有索引，但无法创建或获取观察者。它给出了错误 -

根本原因

Caused by: java.util.zip.ZipException: invalid LOC header (bad signature)

向我建议您的环境中有一个损坏的jar文件。
