Selenium java.lang.NoSuchMethodError启动驱动程序

Question

我已经尝试过以下代码来打开chrome网络驱动程序，然后使用它打开google.com：

import java.io.File;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

 public class Hook{

  private WebDriver driver;

  public void testInitializer(){
    File file = new 
        File(Application.class.getClassLoader()
                .getResource("driver/chromedriver.exe").getFile());
    String driverPath=file.getAbsolutePath();
    System.out.println("Webdriver is in path: "+driverPath);
    System.setProperty("webdriver.chrome.driver",driverPath);
    driver=new ChromeDriver();
}

 public Hook() {

     testInitializer();
     driver.get("https://www.google.com/");
 }

} 

但它抱怨：

driver=new ChromeDriver();

出现以下错误：

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.util.concurrent.SimpleTimeLimiter.create(Ljava/util/concurrent/ExecutorService;)Lcom/google/common/util/concurrent/SimpleTimeLimiter;
    at org.openqa.selenium.net.UrlChecker.<init>(UrlChecker.java:62)

    at org.openqa.selenium.chrome.ChromeDriver.<init>
    at org.openqa.selenium.chrome.ChromeDriver.<init>
    at com.example.demo.Hook.testInitializer(Hook.java:20)

这是完整的依赖项：

<dependency>
                <groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium-java</artifactId>
                <version>3.4.0</version>
            </dependency>

            <dependency>
                <groupId>info.cukes</groupId>
                <artifactId>cucumber-java</artifactId>
                <version>1.2.5</version>
            </dependency>

我想知道，我的代码有什么问题？

请参阅at com.example.demo.Hook.testInitializer(Hook.java:20)上的Exception的最后一行，它是运行时异常，这是因为您的类缺少main方法。

引用Java语言规范 （JLS） A Java virtual machine starts execution by invoking the method main of some specified class, passing it a single argument, which is an array of strings 。 更具体地说，它正在寻找一种应声明为...的方法。

public class Hook {
    ...
    public static void main(String[] args) {
        // body of main method follows
        ...
    }
}
