Project Number not getting updated using Environment Variable : ${PROJECT}

Hello Community,

Project Number not getting updated using Environment Variable : ${PROJECT} but Build Number is getting updated when I use Environment Variable : ${BUILD}. Why is that ? Please advise.

Thanks & regards,

If anyone can advise on this, will be very helpful.

Thanks & regards,

If you go to <root>/env-vars.html/ in your Jenkins you should get a list of env variables that are available to freestyle jobs.
For pipeline jobs visit <root>/pipeline-syntax/globals
