Instructions for writing Groovy files (SshOnRemote)

Hello everyone,

I’m a newbie, learning to write groovy files to run the CICD Jenkins pipeline. I’m having problems with it right now.
I’m writing in Declarative Pipeline style. Write according to stages. Anyone who has experience with it please help me. I will upload photos for your support.

It would be easier if you add the snippet of our pipeline code you encounter issues with, allowing people to take a look at it :slight_smile:
