How to Rebuild Pull Request branch if PR branch is updated

[clayton.han-mitchell]

We currently have automatic builds for PRs against the master branch.  This works fine.  If the author then updates their PR branch (before a merge), there doesn't seem to be a way to have an automated rebuild of that PR branch.

How can we accomplish this?

We are using Jenkins 2 for our build server.

Thank you.

Hi @clayton.han-mitchell,

Welcome to Atlassian Community.

Are you using Bitbucket Server or Cloud? How are you triggering the initial build on a PR branch?

I am using Bitbucket Server and a free app called Pull request notifier for Bitbucket and it allows me to trigger a new build when the PR is changed.

The PRs are coming from Forked repos.  I think we may be stuck by the same issue as this:
