运行简单Java-Selenium项目时遭遇NoClassDefFoundError错误求助

你的代码： #

package XYZ;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class SeleniumScript {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.setProperty("websdriver.chrome.driver", "/Users/MYNAME/Desktop/chromedriver");
        WebDriver driver = new ChromeDriver();
        driver.get("https://google.com/");
        System.out.print(driver.getTitle());
        driver.quit();
    }
}

遇到的错误： #

解决步骤： #

• 修正系统属性拼写错误
  代码里websdriver.chrome.driver多写了一个s，必须改成webdriver.chrome.driver，否则系统无法正确识别ChromeDriver的路径配置。

• 添加Guava依赖库
  错误提示的com.google.common.io.ByteStreams属于Guava（谷歌通用工具库），是Selenium运行的必要依赖。你需要下载与当前使用的Selenium版本匹配的Guava JAR文件，添加到项目的构建路径中，避免版本冲突导致的加载失败。

修正后的代码： #

package XYZ;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class SeleniumScript {

    public static void main(String[] args) {
        // 修正拼写错误
        System.setProperty("webdriver.chrome.driver", "/Users/MYNAME/Desktop/chromedriver");
        WebDriver driver = new ChromeDriver();
        driver.get("https://google.com/");
        System.out.print(driver.getTitle());
        driver.quit();
    }
}
