NoClassDefFoundError exception with SpringBoot in Elasticsearch7.3

I try to create document via high level rest client with:

    Map<String, Object> jsonMap = new HashMap<>();
    jsonMap.put("name", "Bob");
    jsonMap.put("id", "123456");
    IndexRequest indexRequest = new IndexRequest("lead").id("123456").source(jsonMap);
    client.index(indexRequest, RequestOptions.DEFAULT);

But it throws a NoClassDefFoundError: org/apache/lucene/util/BytesRefIterator. The elastic version is 7.3.2. That's the elasticsearch dependency in my pom.

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>${elasticsearch.version}</version>
    </dependency>
    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-high-level-client</artifactId>
        <version>${elasticsearch.version}</version>
    </dependency>

The full stacktrace:

I've found out the cause of the error. There's another dependence in this project which includes a 3.5.0 version of lucene-core.jar. It conflicts with the 8.1.0 version lucene-core.jar in elasticsearch. The program uses the 3.5.0 version actually while the program is running.
