我想打开火狐56与Selenium 3.7发布日期为2017年11月2日，我的Win 8.1的路径也设置在环境变量too.I获取NoClassDefFoundError火狐56.0是不是开放使用Selenium 3.7与壁虎驱动0.19

版本信息：的Java 1.8.091 | Selenium 3.7 | Gecko驱动程序geckodriver-v0.19.1-win64.zip |火狐56

我的代码：从类似的问题

package new_Package; 
    import org.openqa.selenium.WebDriver; 
    import org.openqa.selenium.firefox.FirefoxDriver; 

    public class Selenium_Basics { 
     public static void main(String[] args) throws InterruptedException { 
      System.setProperty("webdriver.gecko.driver", "C:\\Users\\user\\workspace\\Gecko Driver\\geckodriver.exe"); 
      WebDriver driver = new FirefoxDriver(); 
      driver.get("http://www.google.com"); 
     } 
    }

我试图解决方法的计算器和其他网站建议喜欢用不同的Firefox版本尝试，设定DesiredCapabilities或建立二进制文件火狐但什么也仍然工作出。

另外我最近试图在检查点调试。

的可能的复制[NoClassDefFoundError的：在硒为ChromeDriver组织/阿帕奇/ HTTP/HttpEntity]（https://stackoverflow.com/questions/23471340/noclassdeffounderror-org-apache-http-httpentity-in-selenium对于chromedriver） – JeffC

@JeffC：我试过了，但是没有帮助。我甚至试着把Firefox的版本降级到45. –

你说过'我没有配置Selenium独立服务器jar'。那就是问题所在。你需要添加那个jar。 – JeffC

我没有看到任何这样的错误在你的代码块。当JRE找不到Class时，观察到错误NoClassDefFoundError。

简而言之，所需的imports或jar文件不可用。在这种情况下，你需要遵循以下步骤：

删除所有涉及到以前的版本Selenium standalone server & Selenium Java client
仅导入selenium-server-standalone-3.7.0的罐子。
在你IDE内Project菜单，选择选项Build Automatically并执行所有项目的Clean选项。
执行您的测试。
