硒中的线程“ main”中的异常java.lang.NoClassDefFoundError

Question

我知道这个问题已经被问过多次了。但是，我找不到任何答案。

这是我正在使用的东西的一些细节。

Firefox版本-63.0

硒-selenium-java-3.14

我的示例代码-

import java.util.concurrent.TimeUnit;

导入org.openqa.selenium.WebDriver; 导入org.openqa.selenium.firefox.FirefoxDriver;

公共类webdriverdemo {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    String projectLocation = System.getProperty("user.dir");
    System.setProperty("webdriver.gecko.driver","E:\\Proffessional\\FMClarity\\Selenium\\gecko\\geckodriver.exe");  

     WebDriver driver = new FirefoxDriver();
      //Puts an Implicit wait, Will wait for 10 seconds before throwing exception
      driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

      //Launch website
      driver.navigate().to("http://www.calculator.net/");

}

}

但是，我遇到了以下错误。

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableMap
    at org.openqa.selenium.remote.service.DriverService$Builder.<init>(DriverService.java:250)

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 6 more

我的路径是这样给出的。

有人可以告诉我该怎么办才能解决此错误。

预先感谢

Answer 2

问题是您的代码中没有gico-driver

尝试

 public static void main(String[] args) {
        // TODO Auto-generated method stub 
        //complete path to your project
        String projectLocation = System.getProperty("user.dir");
        System.setProperty("webdriver.gecko.driver",your driver full path);
        WebDriver driver = new FirefoxDriver();
        //Puts an Implicit wait, Will wait for 10 seconds before throwing exception
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

        //Launch website
        driver.navigate().to("http://www.calculator.net/");

    }
