+ needs to come at the beginning of the argument representing the couple.
git push origin +localBranchName:remoteBranchName
That’s hard to remember sometimes, so there’s also the
git push origin --force localBranchName:remoteBranchName
But be aware if you push multiple branches with that flag, then they will all be force pushed.
git push origin --force localBranchName:remoteBranchName anotherLocalBranch
In that case, you may not have wanted to force push
anotherLocalBranch, so you should instead use the
+ to specify which ones you want forced.
git push origin +localBranchNameForced:remoteBranchName localBranchNotForced:remoteBranchNotForced +anotherLocalBranchForcePushedToUpstreamTracking
