lang.NoClassDefFoundError：組織/阿帕奇/ HTTP/IMPL /康涅狄格州/ PoolingClientConnectionManager htmlunit.HttpWebConnection.createHttpClient

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();

但是當我想初始化一個無頭硒驅動程序而不是瀏覽器的驅動程序，代碼failes：lang.NoClassDefFoundError：組織/阿帕奇/ HTTP/IMPL /康涅狄格州/ PoolingClientConnectionManager htmlunit.HttpWebConnection.createHttpClient

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

這是爲什麼？

通常，實際的問題是'Caused By：'行顯示的問題;一個'ClassNotFoundException'。如果有幾個'Cause By：'子句，請關注最後一個。 – SJuan76

org.apache.http.impl.conn.PoolingClientConnectionManager

不可用......你有圖書館的地方？

當我在應用程序引擎上運行此代碼時它工作。它怎麼可能是相同的pom.xml 什麼是我需要添加的maven依賴項？ –
