Jenkins: pipelineJob with SCM and static script - github

Question

I would love to use Jenkins job-dsl pipelineJob for creating a build job for a GitHub repository with a static (and centrally maintained) pipeline.
But looking at the documentation (https://jenkinsci.github.io/job-dsl-plugin/#path/javaposse.jobdsl.dsl.DslFactory.pipelineJob-definition) I can either create a cps with a static script or cpsScm with a SCM and a reference to the Jenkinsfile in the repository.
The requirement for having SCM defined comes from the gitParameter plugin, which I want to use for picking a git revision.
Is there a way how I can use a static script for the pipeline together with the SCM?
Update:
This is concretely what I would like to do:
defining a pipeline job
using a git Parameter to select the revision
declare the particular script inline
pipelineJob("test") {
parameters {
gitParameter {
name('revision')
type('PT_BRANCH_TAG')
defaultValue('origin/master')
selectedValue('DEFAULT')
description('')
branch('')
branchFilter('')
tagFilter('')
useRepository('')
quickFilterEnabled(true)
}
}
logRotator {
numToKeep(50)
}
definition {
cpsScm {
scm {
git {
remote {
github("<my-repo>")
credentials('github')
}
branch('$revision')
}
}
script("""
#Library(value='pipeline-lib#master', changelog=false) _
myPipeline projectName: 'test-name'
""")
}
}
}

Answer 1

Pipeline as code has incorporated many functions of jobs-dsl, which is probably why some of the fine tuning capabilities are missing from jobs-dsl's pipelineJob. The examples given on the the Git Parameter plugin page are actually in the pipelines, which could be be the script portion of the cps portion of the jobs-dsl definition. The code quoted in the question could be converted to:
pipelineJob("test") {
logRotator {
numToKeep(50)
}
definition {
cps {
script('''
pipeline {
agent any
libraries {
lib("pipeline-lib#master")
}
parameters {
gitParameter name: 'revision',
type: 'PT_BRANCH_TAG',
defaultValue: 'origin/master',
selectedValue: 'DEFAULT',
description: '',
branch: '',
branchFilter: '',
tagFilter: '',
useRepository: '',
quickFilterEnabled: true
}
stages {
stage('Build') {
steps {
git branch: "${revision}",
url: <myrepo>,
credentialsId: 'github'
// not familiar with what the next line does, assuming it's a pipeline step
myPipeline projectName: 'test-name'
}
}
}
''')
}
}
}
This is for a declarative pipeline. There is also an example of scripted pipeline on the git parameter plugin page.
