Calculate changelog against specific branch using weird ref syntax

[Jordan Coll]

So I've been setting up a new pipeline job, and since we use private branches that are then merged into release branches, I added a  [$class: 'ChangelogToBranch', options: [compareRemote: "jordan/master", compareTarget: "master"]]  to my checkout.

This consistently results in

Using 'Changelog to branch' strategy.
fatal: bad revision '^jordan/master/master'
ERROR: Unable to retrieve changeset

And yeah, '^jordan/master/master' ain't no revision I've ever heard of. Surely I'm doing something wrong?

But looking at the source, I can't figure out how this is supposed to work?

Did it ever?

Why is git whatchanged and not git log?

Is this a git koan? Cus i'm not feeling enlightened.

Ok. compareRemote should obviously be the remote (i.e. origin).

So yeah, works perfectly. Not feeling dumb at all =|
