NoClassDefFoundError: org/elasticsearch/common/xcontent/DeprecationHandler问题

maven

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>6.5.2</version>
        </dependency>

报Exception in thread "main" java.lang.NoClassDefFoundError: org/elasticsearch/common/xcontent/DeprecationHandler

打开es的maven依赖，发现引入的是2.4.6

解决方案，引入es的6.5.2依赖，去掉elasticsearch-rest-high-level-client的es依赖

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>6.5.2</version>
            <exclusions>
                <exclusion>
                    <groupId>org.elasticsearch</groupId>
                    <artifactId>elasticsearch</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
