What kind of 'changes' do you mean? Normally you want to pull
everything from your source control system including whatever command
or script it takes to do the build and just run that command, so any
time you check out that revision/tag you get the same thing whether
jenkins does the build or not. If you are making changes, you should
be committing them back, and generally tagging the ones you want to be
able to easily reference again.
