Git / Jenkins pipeline

[Renato Goncalves]

Hello all,

I am building a NSO (network services orchestrator) automation and would like to ask the best approach regarding reload packages using github as SCM.

Currently every time that I run the pipeline it will clone all packages for a tmp directory, destroy the entire NSO package folder, create a new folder and copy all packages back from the tmp folder inside NSO package folder.

What's the best way to clone only the packages that was changed or don't clone any package at all in case there is no changes to minimise the clone time because in the future I will have more packages and it will take a long time.

Structure of packages folder inside NSO Server:
