You can only use upto 7.5.1 if you are on JDK8.

TestNG 7.6 and above needs JDK11.

So if you want to use TestNG 7.8.0 please use JDK11.

Thanks & Regards

Thank you Krishnan Mahadevan for the response

But as I mentioned in the above message I am using JDK 11 only even though I am getting that error.

TIA

Hari,

No, I don't think that's what is happening here.

The error clearly states that IntelliJ is resolving to JDK8 for your execution. Please have this fixed.

One easy way of ensuring that IntelliJ honours your JDK ask is by setting the JDK version in the maven compiler plugin of your pom file and then importing this project into intellij as a maven project.

Thanks & Regards
