Depends on where have you been working on, if your work is about npcs, htmls, xmls and so (datapack) you can just always compile your server source and c/p the .jar inside game/ and your datapack/config changes won't be affected. If your work is with java files then you should apply each new commit that has been made, manually.

 

Don't even think about:

right click on project. team update to head.

if you've been working core side.
