[FIXED] How can I select a Jenkins pipeline file from a branch specified in a build parameter

Issue

I have a parameterized Jenkins pipeline build. One of the parameters (branch) is the branch to build. The pipeline file is stored in the branch.

In the Pipeline definition, when I use */${branch} as the branch to build in place of */main the ${branch} does not get replaced but shows up as a literal. If I hard code the branch it works as expected.

The ${branch} does get replaced as expected in the pipeline file. So the branch parameter is being set.

Is there a way to get the parameter value into the "Pipeline script from SCM" retrieval from git?

Solution

You can try another approach as following:

1. In pipeline configuration page, change pipeline from SCM to pipeline script

2. Put following pipeline script in input box

node('<Jenkins node label>') {
    
    properties([
        parameters([
            // parameter for branch
        ])
    ])
    
    git url: '', credentailId:'', branch: "${branch}"

    load '<relative path to your Jenkinsfile>'
}
