the command below doesn't work, is there a way to say "run on the diff between the previous commit and this one"?

./pants --changed-since=HEAD~1 ...

what version are you using? for me

./pants --changed-since=HEAD~1 list

works fine to lists files/targets that have changed since the last commit

Same,

./pants --changed-since=HEAD~1 list

is working for me. You may also be interested in

--changed-diffspec

. From `./pants help changed`:

Calculate changes contained within a given Git spec (commit range/SHA/ref).

I.e.,

./pants --changed-diffspec=my_branch list

will show all files touched, independent of what current commit you’re on.

Thak you @hundreds-father-404 and @flat-zoo-31952 I asked a dumb question, I forgot that my Jenkins was configured to do a shallow clone tracking just the last commit (so HEAD~1 doesn't exist)

No that's actually a good thing to watch out for... I was gonna set up my CI to do the same thing this week, so thanks for giving me a heads up
