Java 在maven中运行selenium测试时获取异常

我使用的是java、maven、selenium webdriver。我添加了依赖项“selenium server 2.32.0”、“selenium-java 2.32.0”。但我得到的异常如下： 代码如下：-

public class ABC{
   private static WebDriver webDriver ;
    public static void main(String [] args) throws IOException{
        ChromeDriverService service = new ChromeDriverService.Builder()
        .usingDriverExecutable(
                new File("/root/Downloads/chromedriver"))
                .usingAnyFreePort().build();
        service.start();
        webDriver = new RemoteWebDriver(service.getUrl(),
                DesiredCapabilities.chrome());
          //webDriver = new FirefoxDriver(); 
    }
} 

如您所见，我还创建了firefoxdriver实例，但得到了相同的异常

 Exception in thread "main" java.lang.NoSuchMethodError: org.apache.http.conn.scheme.Scheme.<init>(Ljava/lang/String;ILorg/apache/http/conn/scheme/SchemeSocketFactory;)V
    at org.openqa.selenium.remote.internal.HttpClientFactory.getClientConnectionManager(HttpClientFactory.java:59)
    at org.openqa.selenium.remote.internal.HttpClientFactory.<init>(HttpClientFactory.java:48)
    at org.openqa.selenium.remote.HttpCommandExecutor.<init>(HttpCommandExecutor.java:100)
    at org.openqa.selenium.remote.HttpCommandExecutor.<init>(HttpCommandExecutor.java:81)
    at org.openqa.selenium.remote.RemoteWebDriver.<init>(RemoteWebDriver.java:129).

线程“main”java.lang.NoSuchMethodError中出现异常：org.apache.http.conn.scheme.scheme。（Ljava/lang/String；ILorg/apache/http/conn/scheme/SchemeSocketFactory；）V 位于org.openqa.selenium.remote.internal.HttpClientFactory.getClientConnectionManager（HttpClientFactory.java:59） 位于org.openqa.selenium.remote.internal.HttpClientFactory.（HttpClientFactory.java:48） 位于org.openqa.selenium.remote.HttpCommandExecutor。（HttpCommandExecutor.java:100） 位于org.openqa.selenium.remote.HttpCommandExecutor。（HttpCommandExecutor.java:81） 位于org.openqa.selenium.remote.RemoteWebDriver.（RemoteWebDriver.java:129）。

还添加了“httpclient 4.1.2”。但如果遇到同样的异常，请指导我如何解决此问题，请在服务使用示例下方使用正确的结构（然后通过测试扩展类内的设置）

您能提供完整的堆栈跟踪和代码吗？这里有一个模板，您可以尝试：

    protected static String baseURL = "base url for tests";

        service = new ChromeDriverService.Builder().usingDriverExecutable(new File("pass to your browser")).usingAnyFreePort()
                 .build();
        try {
            service.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    @AfterClass
    public static void createAndStopService() {
        service.stop();

    @BeforeMethod
    public void setUp() throws IOException {

        driver.get(baseURL);
        driver.manage().window().maximize();
    }
    @AfterMethod
    public void tearDown()
    {
        driver.quit();
    }

    public static WebDriver getDriver()
    {
        return driver;
    }
   }
