I followed the steps in this tutorial but im getting something wrong.

The issue is that the tutorial was done on linux system and im using windows
My jenkinsfile is also attached pls help
@BrainBox You are trying to delete the folder like in linux format /var/log/nginx/jenkins-react-app
but if you are using windows give the full location path like c:/ or d:/ or $pwd. Also make sure windows del command has parameter -rf. Make sure to use equivalent windows commands for all the linux command given in the example. Other-way is just create a ubuntu machine or ec2 machine and play around with it.
