Answer 1

Before you start: create a backup

---

Scenario 1: You added the jar files in the most recent commit

Follow these steps:

Delete the jar files:

git remove /path/to/file1.jar
git remove /path/to/file2.jar
...

Commit using amend

git commit --amend

Now push --force to overwrite the remote commit. Attention! do this only if no others have already pulled the commit:

git push --force origin HEAD

---

Scenario 2: You added the jar files not in the most recent commit

If it was not the recent commit you need to identify the commit where you added the jar files. This can be done using

git whatchanged 

for example.

Then you need to rebase that commit using git rebase. Let's say the commit where you added the jars is 79755c4

git rebase -i 79755c4~1

An editor will show up. Replace pick by edit in the line containing 79755c4 and save.

Now delete the jar files as shown above:

git remove /path/to/file1.jar
git remove /path/to/file2.jar
...

Commit this changes using amend:

git commit --amend

Complete the rebase:

git rebase --continue

And push --force the changes to the remote branch. Again, Attention! do this only if no others have already pulled the commit!

git push --force origin HEAD

That's it.
