Error when running FireFox tests on Windows

[Karel Frajtak]

Hi,
can you help me with following issue? Manager correctly gets the driver and then it fails when JVM cannot find class org/openqa/selenium/os/WindowsUtils. I tried to Google this class, but was not able to find out what Maven dependency am I missing.
Thanks,
Karel

You need to review pom.xml

add / change (if other versions) : [dnt use beta drivers :)] [better always us stable]

<dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-firefox-driver</artifactId>
            <version>3.141.59</version>
</dependency>
<dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-chrome-driver</artifactId>
            <version>3.141.59</version>
            <scope>test</scope>
</dependency>
<dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>lift</artifactId>
            <version>3.141.59</version>
</dependency>
        <dependency>
            <groupId>io.github.bonigarcia</groupId>
            <artifactId>webdrivermanager</artifactId>
            <version>3.7.1</version>
            <scope>compile</scope>
</dependency>

Hi,

Same here.

I'm trying to use .browserpath to make it point to a portable Firefox and get the same error message
I'm using the examples directly and the original POM.XML.

java.lang.NoClassDefFoundError: org/openqa/selenium/os/WindowsUtils
at org.openqa.selenium.firefox.FirefoxBinary.locateFirefoxBinariesFromPlatform(FirefoxBinary.java:403)
at org.openqa.selenium.firefox.FirefoxBinary.(FirefoxBinary.java:109)...

I'll add the path to Firefox is correct as the log finds it :
"2020-01-22 13:52:28 [main] DEBUG io.github.bonigarcia.wdm.Preferences - Preference firefox=72 (valid until 2020-01-23 12:09:54)
2020-01-22 13:52:28 [main] DEBUG io.github.bonigarcia.wdm.Preferences - Preference firefox72=0.26.0 (valid until 2020-01-23 12:09:54)
2020-01-22 13:52:28 [main] INFO i.g.bonigarcia.wdm.WebDriverManager - Using geckodriver 0.26.0 (since Mozilla Firefox 72 is installed in your machine)
2020-01-22 13:52:28 [main] DEBUG i.g.bonigarcia.wdm.WebDriverManager - Driver geckodriver 0.26.0 found in cache
2020-01-22 13:52:28 [main] INFO i.g.bonigarcia.wdm.WebDriverManager - Exporting webdriver.gecko.driver as C:\Users\obordere.m2\repository\webdriver\geckodriver\win64\0.26.0\geckodriver.exe
"

SOLVED :
Commented the following in the POM :

org.seleniumhq.selenium
selenium-remote-driver
${selenium.version}
