Spring breaks Selenium dependencies

I want to use Selenium with Spring.

If I use Selenium without Spring, everything just works fine. Whenever I add the Spring dependencies (without Spring code), the following exception is thrown on execution:

Exception in thread "main" java.lang.NoClassDefFoundError: org/openqa/selenium/MutableCapabilities at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:368) at java.net.URLClassLoader$1.run(URLClassLoader.java:362) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:361) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.java:98)

Update: These is my code - very simple, but the firefoxdriver can't even be created..

public class Application {

    private static Logger log = LogManager.getLogger(Application.class);

    public static void main(String[] args) {
        FirefoxDriver driver = new FirefoxDriver(); // exception thrown here

        driver.close();
    }
}

Solution:

By looking at the dependencies of Selenium in the maven repository, I could see which versions were needed for Selenium to run. Then explicitly adding these jars in maven could solve the dependency conflict.

Thank you for your help!

The versions of org.seleniumhq.selenium:selenium-htmlunit-driver and net.sourceforge.htmlunit:htmlunit should be aligned, but you're using 2.29 of the former and 2.21 of the latter. If you remove the versions from your dependency declarations, Spring Boot's dependency management will take care of things for you.
