Hi,

We have an active repository on github, where PRs will be automatically rebased when their base gets a push.

We also have builds that take hours to complete.

During periods of high merge activity this overwhelms our server’s executors with builds that are on commits no longer attached to branch/PRs due to rebase and force push.

How can I automatically abort these builds, so only the latest version of a branch is building? (We use branch as a build parameter, hence determining “same” via parameters would be ideal). These are freestyle declarative jobs using git.

This seems harder than I’d expected!

Thanks,  
Jonny

Thanks! Is it possible to do this with a classic / free style declarative project or do we have to move to pipelines?

I don’t see that option in freestyle project.  
Properlly it is not supported
