When I've worked a bit with my source code, I did my usual thing commit and then I pushed to a remote repository. But then I noticed I forgot to organize my imports in the source code. So I do the amend command to replace the previous commit:
> git commit --amend
Unfortunately the commit can't be pushed back to the repository. It is rejected like this:
> git push origin
! [rejected] master -> master (non-fast forward)
error: failed to push some refs to '//my.remote.repo.com/stuff.git/'
What should I do? (I can access the remote repository.)
I actually once pushed with
.git repository and got scolded by Linus BIG TIME. In general this will create a lot of problems for other people. A simple answer is "Don't do it".
I see others gave the recipe for doing so anyway, so I won't repeat them here. But here is a tip to recover from the situation after you have pushed out the amended commit with --force (or +master).
git reflog to find the old commit that you amended (call it
old, and we'll call the new commit you created by amending
- Create a merge between
new, recording the tree of
git checkout new && git merge -s ours old.
- Merge that to your master with
git merge master
- Update your master with the result with
git push . HEAD:master
- Push the result out.
Then people who were unfortunate enough to have based their work on the commit you obliterated by amending and forcing a push will see the resulting merge will see that you favor
old. Their later merges will not see the conflicts between
new that resulted from your amending, so they do not have to suffer.
