So the point here is that the jars are still in the repository. They are
deleted in your branch, but any objects depending on others (without a lot more
information on your exact repository structure) may cause packed objects to be
sent upstream. The delete is local to your branch, but the delete does not mean
the objects are actually removed from your repository. To actually effect a
removal, the objects would need to be no longer accessible, thus git gc would
remove them permanently. That may be difficult depending on security on your
upstream repository and what you are able to do there. So:
A--- B--- C
If A has no jars, B has the jars and has A as its parent, and C has no jars,
but has B as its parent, then B is still accessible and the jars still exist in
the repository but only not at the HEAD of your branch. Your tree may vary. How
a push gets objects from your repository to your upstream depends on more
information that I have but the point is that the jars still exist in a
distributed sense. Your repository state and the upstream repository state do
not need to be (and are likely not) identical.
