Question

任何人都可以帮助解决这些错误或告诉我是什么导致了这些错误我添加了我从 seleniumHQ.org 下载的文件中的所有 .JAR 文件，但我仍然遇到这些错误：

Answer 1

要在 Mozila Firefox 52.0.2 中使用 Selenium 3.x，您需要：

下载 latest gecko driver 并将其保存在 "C:\your_folder"。
设置系统属性提及 gecko 驱动程序及其在您系统上的绝对路径：

System.setProperty("webdriver.gecko.driver", "C:\your_folder\geckodriver.exe");

接下来将 Webdriver 初始化为：

WebDriver driver = new FirefoxDriver();

最大化浏览器：

driver.manage().window().maximize();

打开一个url：

driver.get("http:\gmail.com");

如果这对你有帮助，请告诉我。
