Hi,

Welcome to the community!

You can compile to whatever version you like, but you need to analyze with at least Java 8.

Hi

Thank you for your quick response.

As mentioned in my query, we are using Java 1.8.0_272 in our environment where sonar scanner is running.

Can you please suggest on this further?

Thanks

Hi Swarnab,

Is $JAVA_HOME set in your environment? And if so, does it point to a lower version than Java 8? When the scanner CLI finds JAVA_HOME it uses that instead of the embedded JVM.
