Make git push fail when there are uncommitted changes

Question

I normally use something like the following to test my changes, and if they are ok, push them to the remote repository:

mvn install && git push

Works great except for that stupid user that has written beautiful code, but forgot to commit it /facepalm/

Is there a way to make git push fail when there are uncommitted changes? Or maybe a separate command that checks for uncommitted changes, so I get something like this:

mvn install && git --clean-only push

or

mvn install && git is-clean && git push

Answer 1

You could probably use mvn install && git diff --quiet --cached && git push. This checks for uncommitted changes. If you'd like to check for unstaged changes, use git diff --quiet instead (or both).
