我正在尝试使用Eclipse编写一个简单的自动化测试，并且在设置它时遇到了问题。我无法启动Firefox。我的代码在下面，然后是错误堆栈。
代码：
package cucumberTest;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class seleniumTest {
private static WebDriver driver = null;
public static void main(String[] args) {
// TODO Auto-generated method stub
//https://www.toolsqa.com/cucumber/first-cucumber-selenium-java-test/
// new instance of frefox driver
driver = new FirefoxDriver();
//Put a Implicit wait, this means that any search for elements on the page
// could take the time the implicit wait is set for before throwing exception
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
//open page
driver.get("http://www.store.demoqa.com");
错误堆栈：这是我尝试在ECLIPSE中运行代码时在控制台窗口中显示的内容。

...表示您的程序无法启动/产生新的 GeckoDriver 服务。
在使用 Selenium v3.x ， GeckoDriver 和 Firefox 来启动新的 GeckoDriver 服务和< em> Firefox浏览器会话，您需要传递 Key webdriver.gecko.driver 以及设置为的 Value GeckoDriver 通过System.setProperty()行的>绝对路径，如下所示：
System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
driver = new FirefoxDriver();
另外，
因此 JDK v8u161 与 Selenium Client v3.141.59 之间存在明显的不匹配。
Test。driver.quit()方法内调用tearDown(){}，以优雅地关闭和销毁 WebDriver 和 Web Client 实例。
