SharedLibrary doesn´t allow git parameter to fetch all branches

[judaondo]

Hello, 

I have the following pipeline that uses a method called "getServiceVersion" from a Shared Library.

#!/usr/bin/env groovy

@Library('mycom')

import com.mycom.*

// Declarative pipeline //

properties([[$class: 'JiraProjectProperty'], buildDiscarder(logRotator(artifactDaysToKeepStr: '', artifactNumToKeepStr: '', daysToKeepStr: '', numToKeepStr: '10')), disableConcurrentBuilds(), parameters([gitParameter(branch: '', branchFilter: '.*', defaultValue: 'origin/integration', description: 'Git Branch', listSize: '10', name: 'branch', quickFilterEnabled: true, selectedValue: 'DEFAULT', sortMode: 'ASCENDING_SMART', tagFilter: '*', type: 'PT_BRANCH')])])

def STAGE

pipeline {
    agent { label 'WindowsSlaveWS2016' }

    options {
        timestamps ()
        ansiColor('xterm')
        disableConcurrentBuilds()
    }

    stages {
        stage('Code checkout') {
            steps {
                echo '<< Checking out source code >>'
                checkout([$class: 'GitSCM', branches: [[name: '${branch}']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'CloneOption', depth: 10, noTags: false, reference: '', shallow: true]], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'gitcredentials', url: 'http://gitserver:8080/myproject']]])
                script {
                    STAGE=env.STAGE_NAME
                }
            }
        }
        stage('Get service version') {
            steps {
                script {
                    STAGE=env.STAGE_NAME
                    getServiceVersion('MY/Path', 'ChangeLog.txt', 'myservice')
                }
            }
        }
       
    }

}

Please notice at the 'git parameter (https://plugins.jenkins.io/git-parameter/)' that fetchs all available branches on the current repository and the selected default vale 'origin/integration'. 

Since I am using shared library it doesn´t load all the available branches and in fact it only displays origin/master instead of origin/integration.

There is a kind of incompatibility? How can I fix this behaviour?

I'd call it a misunderstanding more than an incompatibility.  The git parameter is providing a filter which can limit the set of branches which might be included.  The git parameter cannot expand the set of branches which might be included.  The multibranch pipeline job definition controls the initial set of branches being requested into the workspace.  The branch you're seeking is not being brought into the workspace.

Branch sources that use the REST API to detect changes (GitHub, Bitbucket, Gitea, GitLab) are intentionally optimized to only populate the workspace with the commits for the exact branch being built.  That can save significant time and space with large repositories that contain multiple branches.  If you require more history than the exact branch being built, then you'll likely need to adjust the checkout that you're using to populate the workspace.

I'm not clear why you're using a branch parameter in a Pipeline job.  Isn't it more effective to define a Jenkinsfile in each branch and then allow the multibranch pipeline to create and destroy jobs automatically as branches are created and destroyed?

Hello Mark,

I need to clone 2 repositories, so I can´t place the Jenkinsfile in one repository or another.

I need to place the code directly in the Jenkinsfile inside the job. 

The thing is that branches are not loaded in the git paramater.

Is there any workaround to fix this?

Thank you.

[Mark Waite]

If you need to clone two repositories and can't get the branch names from a git parameter, you could use a string parameter and list the choice of branches yourself.  Or, you could experiment with the git parameter plugin to see if you can find a way to resolve the issue that you're seeing.

Yes, finally I used "String parameter" but that was, what I was trying to avoid... I wanted to help anyone selecting their branch and not typing it.

Thank you for your support :)

Have you installed the multibranch and multipipeline plugins that will help.

The other thing is were you want to set the git repo information in jenkins cred’s jenkins golbal or in the jenkinsfile

don’t mix and match

Which plugins are those? 

Multibranch is this one: https://plugins.jenkins.io/workflow-multibranch/

and multipipeline plugin?

Thank you.
