hi ...

based on that use Chromeoptions to resolve it 

copy paste the code 

ChromeOptions options = new ChromeOptions();
options.addArguments(--remote-allow-origins=*);
webDriver driver = new ChromeDriver(options);
driver.getUrl("paste the url ");

Your stacktrace indicates two things:

1. Your issue is with the appium client and not with selenium.
2. You are perhaps using JDK17 or higher and the appium client libraries are not compliant with JDK17 modules yet. Maybe you can try the recommendations in this SO post (https://stackoverflow.com/q/68117860) or downgrade to JDK11 maybe ?


Thanks & Regards

Hi All,

I am getting this testng error.... Appium page object maven project:

could you help in solving this error

TestNG 7.5 was the last version to work with JDK8.
TestNG 7.6.x onwards, you need JDK11.

The error is saying that you should have been using JDK11, but you are using JDK8.
Refer: https://javaalmanac.io/bytecode/versions/
