Stupid script to see if you have SNAPSHOT in your artifact version or dependencies in you Maven pom.xml

version.sh

#!/usr/bin/env bash

set -euo pipefail

  # Reason for code block with || true on grep commands is because it exists with 1 if nothing is found.
  # Which is perfectly acceptable for the below scenario, so we need to change the exit code to 0. 
  
  # EXPLANATION:
  # "The "||" means "or". If the first part of the command "fails" (meaning "grep e" returns a non-zero 
  # exit code) then the part after the "||" is executed, succeeds and returns zero as the exit code 
  # (true always returns zero)."
