Detailed steps to reproduce the behavior:

Expected behavior

Web driver can be created successfully.

Test script or set of commands reproducing this issue

Source codes to create web driver, and the same codes work for selenium 3.

   public WebDriver create(String testName) {
        logger.debug("create() - create chrome web driver");
        final ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("--no-sandbox");
        chromeOptions.addArguments("disable-infobars");
        chromeOptions.addArguments("--ignore-certificate-errors");
        chromeOptions.setPageLoadStrategy(PageLoadStrategy.NONE);
        chromeOptions.setCapability("screenResolution", "1920x1080");
        chromeOptions.setCapability(CapabilityType.BROWSER_NAME, BrowserType.CHROME);
        chromeOptions.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
        final Map<String, Object> prefs = new HashMap<>();
        prefs.put("credentials_enable_service", false);
        prefs.put("profile.password_manager_enabled", false);
        prefs.put("profile.default_content_settings.popups", 0);
        prefs.put("download_prompt_for_download", false);
        chromeOptions.setExperimentalOption("prefs", prefs);
        final LoggingPreferences loggingPreferences = new LoggingPreferences();
        loggingPreferences.enable(LogType.BROWSER, Level.WARNING);
        chromeOptions.setCapability(CapabilityType.LOGGING_PREFS, loggingPreferences);
        chromeOptions.setCapability("name", testName);
        chromeOptions.setCapability("tz", "America/Montreal");
        logger.info("create() - hub url is {}", hubUrl);
        final RemoteWebDriver remoteWebDriver = new RemoteWebDriver(hubUrl, chromeOptions);
        logger.debug("create() - remote web driver session with id {} created", remoteWebDriver.getSessionId());
        remoteWebDriver.manage().window().maximize();
        return remoteWebDriver;
    }

The issue you’re having is because of Spring. Spring manages version of dependencies in it’s parent pom. When you do

<dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
            <version>4.0.0-alpha-7</version>
</dependency>

You have overridden only the selenium-java artifact, but Spring continues to manages the transitive dependencies. This is why it works if you manually add each dependency (they’re not transitive anymore and you override each).

The proper way to override would be to do:

<properties>
	<selenium.version>4.0.0-alpha-7</selenium.version>
</properties>

And the use it without version>

<dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
</dependency>

@jddipqd It works! Thank you!
