Setting up Salesforce’s CICD using GIT and Jenkins
@CICD @Salesforce @Jenkins @GIT
Objective:
I am tracking various metadata in GIT and need to deploy only the components that were changed but not to redeploy all the metadata from master branch.
Solution:
There could be various options to implement this requirement. I followed a custom route to write a shell script that compares GIT branches (stage vs master) and generates package.xml and a folder “DEPLOY” where only changed components are placed in there. Finally deploys only changed metadata from “DEPLOY” folder.
This script works and was written quickly to fulfill my ask. Feel free to modify based on your requirement.
