Java - Selenium - 无法找到 CDP 版本 94 的精确匹配，因此返回找到的最接近的版本：93

Question

我是 Selenium 新手，在运行代码时遇到有关 CDP 版本的错误。这是我的代码。很简单，目的是登录某个网页。驱动程序打开，填写电子邮件和密码，但到达按钮时，驱动程序关闭。即使我在按钮后再设置等待十分钟。

    public static void main(String[] args) {
            System.setProperty("webdriver.chrome.driver","path/to/my/chromedriver");
            WebDriver driver = new ChromeDriver();
            WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
            try {
                driver.get("https://someweb.com/");
                driver.findElement(By.name("Email")).sendKeys("anemail@email.com");
                driver.findElement(By.name("Password")).sendKeys("randomPass");
                driver.findElement(By.xpath("//*[@id=\"login-form\"]/button")).sendKeys(Keys.ENTER);
            } finally {
                driver.quit();
            }

        }

我在日志中收到以下警告

我的 pom 中有以下依赖项

我不明白司机为什么突然下车。Chrome 和 ChromeDriver 版本为 94.0.4606.61。提前致谢！

根据Selenium文档，

• 版本v4.0.0-rc-1支持CDP版本：85、92、93。

但您正在使用和94的版本。所以请将您的依赖项更新到最新版本 ChromeChromeDriverv4.0.0-rc-2

依赖关系：

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>4.0.0-rc-2</version>
</dependency>
