java - lang.NoClassDefFoundError : org/apache/http/impl/conn/PoolingClientConnectionManager htmlunit. HttpWebConnection.createHttpClient

Question

这个问题已经有答案了:

Why am I getting a NoClassDefFoundError in Java? (31 个回答)

已关闭 6 年前。

public static void main(String[] args) throws IOException {
    RbnRunner runner = new RbnRunner();
    runner.run();

}

public void run() throws IOException {

    System.setProperty("webdriver.chrome.driver", "/Users/me/samples/Adam_milford/src/chromedriver");

    WebDriver driver = new ChromeDriver();

但是当我想初始化 headless Selenium 驱动程序而不是 Chrome 驱动程序时，代码失败:

public static void main(String[] args) throws IOException {
    WebDriver driver = new HtmlUnitDriver();

这是为什么？
