Code works on the developer's machine but fails in Jenkins. How could Git be involved?

Core Summary

Stop guessing about the code and compare commit SHAs first. CI often builds a different commit than the developer tested: a merge commit, a stale workspace, a shallow clone, missing submodules, or a file that's gitignored locally but needed at build time. Only once the SHAs match is it worth looking at the code.

Hint 1: Compare the SHA the developer tested with the SHA CI built

Hint 2: Many CI systems build a merge commit, not your branch tip

Hint 3: Files that exist locally may simply not be in the repo
