"Updates were rejected because the tag already exists" when attempting to push in SourceTree

Question

You should also be able to solve this in git bash (click on "Terminal" button in the Source Tree UI). Type:

git pull --tags

If you have not made any local changes to the tag that you want to keep, then you can remove tag that was rejected because it already exists (example_tag in this case):

1. Right-click the tag and choose to delete it (be sure to uncheck the Remove tag from all remotes checkbox).
2. Choose the Fetch option (Fetch and store all tags locally does not have to be enabled).
3. You should now have that tag that was just deleted back, and attempting to Push will no longer show that error message.

The reason this is common in SourceTree is because the Push all tags option is set to on by default. (Another way to hide this error is to uncheck that option.)

git pull --tags works really well but sometimes you can get an error even with this command. Example error message:

 ! [rejected]        example_tag      -> example_tag  (would clobber existing tag)

This can be solved with the command: git pull --tags -f

-f stands for force.

Uncheck push all tags at the bottom of the UI when you confirm your git push

Make sure you uncheck the "Push all tags" button while push.
