ES报错：org.elasticsearch.client.Request.＜init＞(Ljava/lang/String；Ljava/lang/String；)V

今天ES执行时，报这个错误：

org.elasticsearch.client.Request.<init>(Ljava/lang/String;Ljava/lang/String;)V

Maven：
 

     <!-- elasticSearch start -->
        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>6.2.1</version>
        </dependency>

        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>6.2.1</version>
        </dependency>
        <!-- elasticSearch end  -->

对ES操作，报如下错误：

java.lang.NoSuchMethodError: org.elasticsearch.client.Request.<init>(Ljava/lang/String;Ljava/lang/String;)V

问题定位及分析
通常出现java.lang.NoSuchMethodE
