我正在尝试使用Java代码自动化Node \ Hub配置过程。为此，我从网上获取代码并在我的测试代码中执行所需的功能更改并实现。在执行代码时，我可以打开firefox浏览器，但之前 myDriver.get（＆＃34; http://www.google.com＆＃34） 声明，执行失败并显示以下错误。
任何人都可以为此解决问题吗？
先谢谢。

我认为WebDriver实例化了两次，因此在实例化驱动程序后无法打开浏览器。
java.util.concurrent.ExecutionException: org.openqa.selenium.WebDriverException: java.lang.reflect.InvocationTargetException
答案 1 :(得分：0)
Selenium版本应与Firefox浏览器版本兼容。尝试使用不同版本的浏览器。
