How to add a build selector as a parameter? - jenkins

Question

I have two jobs:
Build job
Deployment job
I copy the artifacts (jars) generated in the first job to the second job and deploy them to an environment.
properties([
parameters(
[
string(
name: 'buildnumber',
description: 'Buildnumber to deploy'
),
choice(
name: 'env',
choices: ['qa', 'stage', 'prod'],
description: 'Environment where the app should be deployed'
)
]
)
])
node{
stage('Copy artifacts'){
copyArtifacts(projectName: 'my-demo-build-job/master', selector: specific(params.buildnumber))
}
stage('Deploy'){
sh 'Deploying to the specified environment '
}
}
With this I have to manually check the latest/successful builds and put that as a parameter. Is there a way so that we can get a dropdown with all the successful build sorted by build number as a selector from the other job?

Answer 1

You can use the Extended Choice Parameter Plugin for achieving what you want with the help of a groovy script.
You will need to define an extended choice parameter of type Single Select, as a Source for Value choose Groovy Script, and as a groovy script use something like the following:
def job = jenkins.model.Jenkins.instance.getItemByFullName('my-demo-build-job/master')
return job.builds.findResults{
it.result == hudson.model.Result.SUCCESS ? it.getNumber().toInteger() : null
}
This script will go over all the build of the configured job and filter out only the successful builds - which will be returned as the select-list options for the parameter.
The configuration in the pipeline will look like:
properties([
parameters([
extendedChoice(name: 'buildnumber', type: 'PT_SINGLE_SELECT', description: 'Buildnumber to deploy', visibleItemCount: 10, groovyScript:
'''def job = jenkins.model.Jenkins.instance.getItemByFullName('my-demo-build-job/master')
return job.builds.findResults { it.result == hudson.model.Result.SUCCESS ? it.getNumber().toInteger() : null }''',
choice(name: 'env', choices: ['qa', 'stage', 'prod'], description: 'Environment where the app should be deployed'),
])
])
