Adding multiple repositories to a Pipeline

When you add a a new Pipeline job, selecting Pipeline script from SCM displays a form which allows you to select the repository from which the jenkinsfile for the pipeline is loaded. However, it also allows you to add multiple repositories, and each repository added requires its own jenkinsfile.

What does Jenkins do with the Jenkinsfiles from each of the repositories added?

It doesn’t seem to be executing all of them, it seems only one is executed, what’s the logic used to select the jenkinsfile which gets executed?

Is there any documentation out there which explains this well (I’ve yet to find any) ?

i don’t think it requires it. What behavior are you seeing?

I would just recommend using the git or checkout step to grab the extra code your want instead of using the source in the config. The syntax generator will help you fill out all the right parameters

Hi

Thanks for the reply.

I’m talking about the Pipeline script from SCM…

In this particular example i have added two repositories

testcommon and
testscheduler

only testcommon has a jenkinsfile. So after changes to common are made… it finds the JenkinsFile and successfully completes. Whereas when you make changes in testscheduler click the build now button you get

If you check into common again it’ll pull the jenkins file out of common and run successfully.

I’ve actually got about 5 real repositories and when i run a pipeline job on it, with changes pushed to two or more of the repositories, it seems to be randomly selecting only one of the repositories to pull the jenkins file, I might have thought it pulls the jenkins file only out of the first repository, or if it didn’t work that way, that it pull jenkins files out of each of the repositories which have had changes since the previous build and execute each of them. What it actually does baffles me and makes me wonder if i understand the purpose of it.
