java - selenium 3.4.0/timeouts() 隐式等待

Question

我将我的应用程序从 selenium 3.0.1 “移动”到 3.4.0 ，现在我得到了这个当我尝试设置 implicitlyWait 时出现异常

import java.util.concurrent.TimeUnit;
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

我得到以下异常

the exception is org.openqa.selenium.WebDriverException: setTimeouts

我创建了一个简单的程序，我得到了同样的错误 org.openqa.selenium.WebDriverException: setTimeouts

，不明白这个..

package test.com.gmv.esaccsop.selen;

import java.util.concurrent.TimeUnit;

import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class test2 {

    @Test
    public void openyahooTest() {
            System.setProperty("webdriver.gecko.driver", "c:/geckodriver/18-64/geckodriver.exe");
        WebDriver driver = new FirefoxDriver();
        System.out.println("after Init the driver");

        driver.get("http://localhost:8080/web/guest");
        System.out.println("after get localhost ");


        try
        {
            driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
        }
        catch (org.openqa.selenium.WebDriverException e) 
        {
            e.printStackTrace();
        }   
        System.out.println("after wait  ");
        WebElement title = driver.findElement(By.xpath("//title"));


    System.out.println("*" + title.getAttribute("text") + "*");

    System.out.println("********************************************************");

    driver.quit();

}

同样的错误

after Init the driver
after get localhost
