我正在使用配置了 SSL 的弹性搜索 5.6.15。我启动并运行了集群，并且从我的客户端服务器上我可以使用 curl 检查弹性集群的运行状况。
弹性搜索文档 https://www.elastic.co/guide/en/x-pack/5.6/java-clients.html
代码尝试
Settings settings = Settings.builder()
.put("cluster.name", clusterName)
.put("xpack.security.user", userNamePassword) // Adding Username and Password in XPack Settings for ES.
.put("xpack.security.transport.ssl.enabled", "true")
.put("xpack.ssl.key", configFolderPath + "/ssl/client.key")
.put("xpack.ssl.certificate", configFolderPath + "/ssl/mycrtfile.crt")
.put("xpack.security.transport.ssl.certificate_authorities", configFolderPath + "/sam/ssl/mychainbundle.crt")
但是，当我尝试使用上面的代码调用弹性搜索集群时，它给了我以下异常：
ElasticsearchException[Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin]]; nested: InvocationTargetException;
nested: ElasticsearchException[failed to initialize a KeyManagerFactory]; nested:
