java - WebDriver 和 ChromeDriver : Unable to fix org/json/JSONException error

Question

我刚开始使用 Selenium WebDriver。我正在尝试使用 ChromeDriver，以下是我的代码:

public class WebScraper  {
    public WebScraper() {

    }

    public WebDriver driver = new ChromeDriver();

    public void openTestSite() {
        driver.navigate().to("https://google.com");
    }


    public void enter(String word) {

         WebElement query_editbox = 
         driver.findElement(By.id("query")); 
         query_editbox.sendKeys(word);
         query_editbox.sendKeys(Keys.RETURN);

    }

//    public void getText()  {
//        //List<WebElement> searchResults = 
//        driver.findElements(By.xpath("//div[@id='mid']/div")); 
//        // Writer writer = new BufferedWriter(new 
//        OutputStreamWriter(new FileOutputStream("status.txt"), 
//        "utf-8"));
//        //int[] index = {0};
//
//    WebElement result=driver.findElement(By.id("mid"));
//    System.out.println(result.getText());
//}

public static void main(String[] args) throws IOException  {
    System.setProperty("webdriver.chrome.driver", "chromedriver");        
    System.out.println("Hello");

    WebScraper webScraper = new WebScraper();
    webSrcapper.openTestSite();
    webSrcapper.enter("avoir");
    //webSrcapper.getText();
    System.out.println("Hello");

}
}

我收到以下错误:

    ... 6 more

有人可以帮我解决这个问题并告诉我为什么我首先会收到此错误吗？

谢谢!

错误

Exception in thread "main" java.lang.NoClassDefFoundError: org/json/JSONException

是因为它缺少依赖org.json添加这个https://mvnrepository.com/artifact/org.json/json/20180813
