"C:\Program Files\Java\jdk-15.0.2\bin\java.exe"

That looks like JDK 15 rather than JDK 17. Are you sure that you're running JDK 17?

[shahnihir]

yes its 17, same error in both, Open jdk 15 and 17

Is this project being actively supported?

The most recent release is from June 2023 and refers to using Java 11 language features where possible. In that sense, I think that it is actively supported, at least as the library is being used in the Jenkins project.

The most recent commit was 3 weeks ago and adds testing on Java 21. In that sense, I think that it is actively supported, at least as the library is being used in the Jenkins project.

If "actively supported" means something different for you, then you'll need to elaborate further on what you're trying to achieve.
