CloudBess PR Builder Question: PR Jobs for different target branches?

[Richard Zowalla <rz...@apache.org>]

Hi all,

I was pointed from INFRA Slack to builds@apache.org to ask my question.

I was looking at [1]. In TomEE we have the situation, that we have
different branches to maintain different versions of TomEE (which are
built with different Java versions and different Maven versions) such
as 9.x, 8.x, 7.1.x, 7.0.x, etc

We have PRs enabled on GitHub and would like to automatically build
them via Jenkins. This setup worked okaish in the past (as we build
with the same baseline: Java 8).

Is it possible to setup the CloudBees PR Builderto only build PRs
targeting a specific branch, i.e.

- If I have a PR which targets "master" -> a specific jenkins job
should build it: 
https://ci-builds.apache.org/job/Tomee/job/master-pull-request/

- If I have a PR which targets "tomee-8.x" -> another jenkins job
should built it: 
https://ci-builds.apache.org/job/Tomee/job/pull-request/

We experimented with branch specifiers, but that does not seem to be
the solution as the PRs are built regardless the target branch
specified in the PR. 

If you have some hints or can point me to an example, that would be
very much appreciated.

Thanks in advance,
Richard
