线程“main”中的异常java.lang.IllegalStateException：驱动程序可执行文件的路径必须由webdriver.gecko.driver系统设置

Question

在发布并给出解决方案之前，我已经厌倦了所有的事情，但仍然得到了相同的错误FireFox，Chrome & Internet Explorer。

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.firefox.FirefoxDriver; 


public class Search { 

public static void main(String[] args) throws InterruptedException { 
    WebDriver driver = new FirefoxDriver(); 
    System.getProperty("webdriver.gecko.driver", 
      "C:\\Users\\nitin\\Downloads\\geckodriver-v0.18.0- 
    win64\\geckodriver.exe"); 
    driver.get("http://www.wikipedia.org"); 
    WebElement link; 
    link = driver.findElement(By.linkText("English")); 
    link.click(); 
    Thread.sleep(5000); 
    WebElement searchbox; 
    searchbox = driver.findElement(By.id("searchInput")); 
    searchbox.sendKeys("Software"); 
    searchbox.submit(); 
    Thread.sleep(5000); 
    driver.quit();

WebDriver driver = new FirefoxDriver();
