[36Tushar]

What happened?

I am using Eclipse -> Maven with Selenium version 4.25.0 . I have almost tried every solution present on github , youtube and chatgpt still not able to resolve the issue .

i have tried to run my code even after adding dev.failsafe dependency ->

<dependency>
            <groupId>dev.failsafe</groupId>
            <artifactId>failsafe</artifactId>
            <version>3.3.0</version>
</dependency>

still facing the same issue.

here is my pom file -> pom file .docx

How can we reproduce the issue?

{ public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "\"/Users/tusharyadav/Documents/chromedriver\"");
        var driver = new ChromeDriver();
        driver.get("https://www.google.com");
}

}

@36Tushar you should remove the duplicate selenium-java and testng entries from your pom.xml. Alter this run mvn dependency:tree to check all selenium jars are from the same release version.

I have removed and checked versions and all selenium jars are from same release versions .

I am also facing this same issue. Is there a solution for this?

[joerg1985]

I don't have a solution, but a workaround for now. This seems to be related to the java module system. Adding requires dev.failsafe.core; to my module declaration did help.

Thanks will try it and let you know.
