Java - Selenium - 无法找到与 CDP 版本 94 完全匹配的版本，因此返回找到的最接近的版本：93

Question

I'm new to Selenium and I'm having an error about CDP versions when running my code. This is my code. It's simple, aiming to log in into some web page. The driver opens, fills the email and password but when reaching the button, the driver closes. Even if I set another wait for ten minutes after the button.

    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();
            }

        }

I get the following warning in my log

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

And I have the following dependencies in my pom

    <dependencies>
        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
            <version>4.0.0-rc-1</version>
        </dependency>
        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-chrome-driver</artifactId>
            <version>4.0.0-rc-1</version>
        </dependency>
        <dependency>

            <version>4.0.0-rc-1</version>
        </dependency>
    </dependencies>

I have no idea why the driver exits so suddenly. Chrome and ChromeDriver version is 94.0.4606.61. Thanks in advance!

As per Selenium documentation,

• The version v4.0.0-rc-1 supports CDP versions: 85 , 92 , 93 .

But you are using 94 version of Chrome and ChromeDriver . So please update your dependencies to latest version v4.0.0-rc-2

Dependency :

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