I had several commits on my branch, all related to the same change. Instead of merging all the commits into master, I wanted to squash all of them into one, and merge the single commit. Less junk on the master branch that way.
This https://gist.github.com/nicholashagen/2855167 has a shows a very nice way to merge and squash together. But since I use bitbucket(aka stash) and pull requests, the git merge --squash command doesn't work.
I had been looking for a slick way of squashing commits before generating a pull request, and recently found it.
I had 4 commits I wanted to squash (all the ones with the comment "Add sonar jobs for all apps") on the branch feature/add-sonar:
git log shows me the commit IDs
git rebase -i allows me to squash the ones from the current point (HEAD) back to the last n commits (in my case n = 4)
At this point I got an editor open up with the list of the last 4 commits, so I could do something with them:
Notice that the commits are in reverse chronological order - so the oldest one shows up first. I wanted to pick the oldest one, and squash the others. So I changed the text to look like this:
Ctrl-X (to save)
y (to confirm)
The rebase is successful:
Now all you have to do is push. But you need to force push.
Now git log shows only 1 commit:
Now you can merge that single commit in any way you choose :)
