Revert a merged pull request on Bitbucket

I've created a pull request and I've merged it to an wrong branch. How can I revert it?

As far I've been to figuring out taking a look over there, I'm able to hard reset the destination branch... but, how about the pull request in origin repository?

I'm using Bitbucket and I've created the pull request from SourceTree (opening the Bitbucket page).

I've three branches I'm working on: master, dev and create-alias. create-alias was set up from dev and dev from master: master -> dev -> create-alias. The problem is I made a pull request from create-alias and I did merge it into master instead of dev.

I'm working on create-alias branch right now. The last commit on create-alias is 6ee20f9 and the merged commit on master is be36f72.

Could you write me down a bit about who to step-by-step revert it?

As far I've been able to figure out:

1. checkout on master.
2. revert -m 1 6ee20f9.
3. push.
4. checkout on create-alias and going on working.

Isn't it?

Unfortunately, there is no "Revert Pull Request" feature on Bitbucket as of this writing, but a feature request exists for it.

Note: Before you proceed, make sure your working copy is clean, with no uncommitted or unpushed changes.

So, you'll have to revert the merge in Git. First, find the SHA hash of the merge commit.

On the command line, this is:

git checkout <branch>
git pull
git log

Then, we revert the merge commit and push it:

git revert -m 1 <SHA-1>
git push

In SourceTree, first checkout the branch in question, then Pull. Find the merge commit in the log window, then right click it, and click Copy SHA-1 to Clipboard.... Then go to Actions --> Open in Terminal. Once the terminal opens, type:

git revert -m 1 <SHA-1 (from clipboard)>
git push

Unfortunately, SourceTree doesn't have a way to simply right-click and revert a merge, but a feature request exists for it.

Bitbucket has a "revert" button on Pull Requests now.

Note it doesn't automatically update the branch the original PR was merged into it. It creates a new branch with a commit that reverts the PR:

You then can create a PR from this branch and merge it.

Bitbucket now has the 'Merge Pull Request' feature released. Follow this link to learn more.

With bitbucket, we can't revert a merged pull request. The revert option which is present in the pull request will create a new branch with a new head(before this commit). That branch later you have to merge into your master/release branch. This is all as communicated by the official Bitbucket doc.
