Hello,
I'm just getting started with Jenkinsfiles (Scripted) after using Job DSL
for a few years. I'm playing around with the Multibranch Pipeline plugin
(using GitHub Branch Source), as it seems like an incredibly easy way to do
things. I've already got a build running in a few dozen lines that would've
taken me a lot more with Job DSL.
I have one bit of extreme confusion though:
I create a new "Multibranch Pipeline" job with configuration "by
Jenkinsfile", and configure it with a GitHub Branch Source. That's
wonderful; it picks up all my branches and builds them as desired.
However, the default configuration of the GitHub Branch Source plugin (as
seen through the UI) has "Build origin branches also filed as PRs" checked
(true) and "Build origin PRs (merged with base branch)" unchecked (false).
I can't seem to figure out how to use my Jenkinsfile to change those
settings. I tried using the properties construct:
properties([
[
$class: 'org.jenkinsci.plugins.github_branch_source.GitHubSCMSource',
buildOriginBranch: true,
buildOriginBranchWithPR: false,
buildOriginPRMerge: true,
buildOriginPRHead: false,
buildForkPRMerge: true,
buildForkPRHead: false
]
])
But that just results in
java.lang.ClassCastException:
org.jenkinsci.plugins.github_branch_source.GitHubSCMSource cannot be cast to
hudson.model.JobProperty
We *only* define our job configuration in code (currently using Job DSL
almost everywhere), and I'm trying to work on a first example of
Jenkinsfiles, but can't get past this one stumbling block.
I've spent over 8 hours on this by now, to no avail. I see that the
pipeline reference for workflow-multibranch
<https://jenkins.io/doc/pipeline/steps/workflow-multibranch/#code-properties-code-set-job-properties>
and for workflow-cps-global-lib
<https://jenkins.io/doc/pipeline/steps/workflow-cps-global-lib/> make
reference to *GitHubSCMSource*, and appear to have options for what I want,
but I can't seem to find any examples of using either that make sense to me
and couldn't get it working on my own (partly because the formatting of
those documentation pages seems to be broken).
Emphatic thanks for anyone who can point me in the right direction or offer
help with this.
Thanks,
Jason Antman
