问题描述

我正在尝试执行以下代码，但是在运行时出现错误"java.lang.NoClassDefFoundError:org/apache/commons/exec/Executor".我也添加了"Common-Exec jar"文件，但是它不起作用.我是否需要添加任何其他jar文件?

I am trying to execute the below code but getting error "java.lang.NoClassDefFoundError: org/apache/commons/exec/Executor" while running. I have added "Common-Exec jar" file too but it is not working. Do I need to add any other jar file ??

package cross_browser;
import org.testng.annotations.Test;
import org.testng.annotations.Parameters;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;

public class NewTest {
    WebDriver driver;
    String url;

  @BeforeClass
  @Parameters({"browser"})
  public void beforeTest(String browser) {
      url = "https://www.facebook.com";
      if (browser.equalsIgnoreCase("chrome"))
      {
          System.setProperty("webdriver.gecko.driver", "C:\\Users\\Prateek\\Desktop\\Drivers\\geckodriver.exe");
          driver = new FirefoxDriver();
      }
      if (browser.equalsIgnoreCase("firefox"))
      {
          System.setProperty("webdriver.chrome.driver", "C:\\Users\\Prateek\\Desktop\\Drivers\\chromedriver.exe");
          driver = new ChromeDriver();
      }
      driver.manage().window().maximize();    
  }

  @Test
  public void Test() {
      driver.get(url);
      driver.findElement(By.id("email")).sendKeys("Prateek");
      driver.findElement(By.id("password")).sendKeys("Prateek");
      driver.findElement(By.id("login")).click();
  }

  @AfterClass
  public void afterTest() {
      driver.quit();
  }

}

推荐答案

尝试添加此依赖项，它对我有用

Try adding this dependency, it worked for me

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-exec</artifactId>
    <version>1.3</version>
</dependency>
