selenium3.3+Firefox54（最新版） WebDriver报错？
初学者，配置好了一切，网上找了一些demo代码如下：
package Selenium_Java;
import java.io.File;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
public class test111 {
public static void main(String[] args) {
//System.setProperty("webdriver.firefox.bin", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
WebDriver driver = new FirefoxDriver();//创建火狐
driver.get("http://www.baidu.com");//打开百度
driver.manage().window().maximize();//最大化
WebElementelement = driver.findElement(By.id("kw"));
element.sendKeys("HelloWorld");//输入值china
driver.findElement(By.id("su")).click();
System.out.println("asdasd");
}
}报错如下：
Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver. The latest version can be downloaded from https://github.com/mozilla/geckodriver/releases

at Selenium_Java.test111.main(test111.java:22)报错那行是：WebDriver driver = new FirefoxDriver();//创建火狐
我看别人demo都是有上面那一段就打开了火狐浏览器
下面报错看不懂。。。求大神支援下。很不懂
这行代码报错：driver = new FirefoxDriver();//创建火狐
这是为什么，但是我的火狐浏览器是打开了的
1.指定geckodriver的路径
System.setProperty("webdriver.gecko.driver", "D:\\Program Files\\Mozilla Firefox\\geckodriver.exe");
2.如果还是报错，更换selenium的jar包，更换为selenium-server-standalone-3.4.0.jar；
我的火狐浏览器的版本是51
