BDD-Java（行为驱动开发）是一种软件开发方法论，结合了测试驱动开发（TDD）和领域驱动设计（DDD）的思想。Cucumber是一个BDD框架，可以使用Java编写Cucumber测试脚本，并生成HTML报告。

要在Cucumber中只生成场景标题而不包含步骤，您可以使用自定义的Cucumber插件来实现。下面是一个示例代码，展示了如何使用Cucumber的钩子（hooks）和自定义的插件来实现这个功能：

1. 创建一个自定义的Cucumber插件类，继承自Cucumber的AbstractReporter类，并覆盖相应的方法：

import cucumber.runtime.CucumberException;
import cucumber.runtime.io.URLOutputStream;
import cucumber.runtime.io.WriterOutputStream;
import cucumber.runtime.formatter.ColorAware;
import cucumber.runtime.formatter.Format;
import cucumber.runtime.formatter.Stats;

import java.io.File;
import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.nio.charset.StandardCharsets;
import java.util.List;
import java.util.Map;

public class CustomHtmlReporter extends AbstractReporter implements ColorAware {
    private final HtmlFormatter htmlFormatter;

    public CustomHtmlReporter(File htmlReportDir) {
        htmlFormatter = new HtmlFormatter(htmlReportDir);
    }

    @Override
    public void setMonochrome(boolean monochrome) {
        htmlFormatter.setMonochrome(monochrome);
    }

    @Override
    public void setEventPublisher(EventPublisher publisher) {
        super.setEventPublisher(publisher);
        publisher.registerHandlerFor(TestRunStarted.class, htmlFormatter::setEventPublisher);
        publisher.registerHandlerFor(TestCaseStarted.class, htmlFormatter::setEventPublisher);
        publisher.registerHandlerFor(TestStepStarted.class, htmlFormatter::setEventPublisher);
    }

    @Override
    public void setStrict(boolean strict) {
        htmlFormatter.setStrict(strict);
    }

    @Override
    public void syntaxError(String state, String event, List legalEvents, String uri, Integer line) {
        htmlFormatter.syntaxError(state, event, legalEvents, uri, line);
    }

    @Override
    public void uri(String uri) {
        htmlFormatter.uri(uri);
    }

    @Override
    public void feature(Feature feature) {
        htmlFormatter.feature(feature);
    }

    @Override
    public void scenarioOutline(ScenarioOutline scenarioOutline) {
        htmlFormatter.scenarioOutline(scenarioOutline);
    }

    @Override
    public void examples(Examples examples) {
        htmlFormatter.examples(examples);
    }

    @Override
    public void startOfScenarioLifeCycle(Scenario scenario) {
        htmlFormatter.startOfScenarioLifeCycle(scenario);
    }

    @Override
    public void background(Background background) {
        htmlFormatter.background(background);
    }

    @Override
    public void scenario(Scenario scenario) {
        htmlFormatter.scenario(scenario);
    }

    @Override
    public void step(Step step) {
        // 不处理步骤信息
    }

    @Override
    public void match(Match match) {
        htmlFormatter.match(match);
    }

    @Override
    public void result(Result result) {
        htmlFormatter.result(result);
    }

    @Override
    public void embedding(String mimeType, byte[] data) {
        htmlFormatter.embedding(mimeType, data);
    }

    @Override
    public void write(String text) {
        htmlFormatter.write(text);
    }

    @Override
    public void close() {
        htmlFormatter.close();
    }

    @Override
    public void eof() {
        htmlFormatter.eof();
    }

    @Override
    public void done() {
        htmlFormatter.done();
    }

    @Override
    public void before(Match match, Result result) {
        htmlFormatter.before(match, result);
    }

    @Override
    public void after(Match match, Result result) {
        htmlFormatter.after(match, result);
    }

    @Override
    public void setStrict(boolean strict, boolean strictJava) {
        htmlFormatter.setStrict(strict, strictJava);
    }

    @Override
    public void setEventPublisher(EventPublisher publisher) {
        htmlFormatter.setEventPublisher(publisher);
    }

    @Override
    public void setMonochrome(boolean monochrome) {
        htmlFormatter.setMonochrome(monochrome);
    }

    @Override
    public void setTags(List tags) {
        htmlFormatter.setTags(tags);
    }

    @Override
    public void setTagFilter(TagFilter filter) {
        htmlFormatter.setTagFilter
