Git/source tree move specific commits at branch B to branch A

Question

I have an accident when develop. I have two commits which need at branch A but I pushed to branch B. So now, I want to move those commit to branch A and then remove them from branch B. Please view image for detail:

Answer 1

First, go to branchA and cherry-pick the two commits you want to pick here.

$ git checkout branchA
$ git cherry-pick <commit1>       # commit1 = 0a18e0f   
$ git cherry-pick <commit2>       # commit2 = e604ce4

$ git push origin HEAD            # push to remote

Now remove the two commits from branchB by revert or rebase. Revert is preferable because it does not change git history.

Revert:

$ git checkout branchB
$ git revert <commit1>
$ git revert <commit2>
$ git push origin HEAD

Rebase:

$ git checkout branchB
$ git rebase -i efb2443         # go back to the commit before the two commmits you want to remove

Now comment out (adding `#` before the commit hash) the two commits you want to remove.

$ git push -f origin HEAD       # you need to force(-f) push as history is changed here by rebasing
