我一直在尝试在apache光束管道中使用Elasticsearch chIOAPI。我无法连接到elasticsearch。任何帮助都会很棒。

我的JAR版本：

org. apache2.0-sdkjava-core：2.37.0

org. apache2.0-sdk s-java-io-弹性搜索：2.37.0

我的弹性版本是：8.1.2

留档说只支持v2. x

链接：https://beam.apache.org/releases/javadoc/2.0.0/org/apache/beam/sdk/io/elasticsearch/ElasticsearchIO.html

我不能使用最新版本的弹性吗？有人尝试过让它使用最新版本吗？

我的管道：

public class Test {
    public static void main(String[] args) {
        PipelineOptions options = PipelineOptionsFactory.create();

        org.apache.beam.sdk.Pipeline pipeline = org.apache.beam.sdk.Pipeline.create(options);

        PCollection<FileIO.ReadableFile> files = pipeline.apply(
                        FileIO.match().filepattern("/path_to_files/**")
                                .continuously(
                                        Duration.standardSeconds(10),
                                        Watch.Growth.never()))
                .apply(FileIO.readMatches());

        PCollection<FileIO.ReadableFile> filteredFiles =  files.apply(Filter.by(new EndsWithFilter("Dummy.txt")));
        
        filteredFiles.apply(ParDo.of(new DummyFileProcessor())).apply(ElasticsearchIO.write().withConnectionConfiguration(ElasticsearchIO.ConnectionConfiguration.create(new String[]{ "http://****:9200" }, "***").withUsername("***").withPassword("***")));

        pipeline.run().waitUntilFinish();
    }
}

请找到Stacktrace，上面说找不到弹性搜索版本
