can variables stored in git repo file be used in jenkins build

Question

I am creating a Jenkins Freestyle build and I'm pulling a git repo in the SCM. One of the files in the repo contains content related to the build. How can I pass them as variables and use them during the build. Are there any plugins which can be leveraged?

Answer 1

If you are using a declarative pipelien (you can easily convert your freestyle job into such a pipeline), you can read the file, and trigger another job with, as parameters, content from that file.

You can see a (close-ish) example in "Reading file from Workspace in Jenkins with Groovy script"

pipeline {
   agent any

   stages {
      stage('Hello') {
         steps {
            script{
               git branch: 'Your Branch name', credentialsId: 'Your crendiatails', url: ' Your BitBucket Repo URL '
          
               def filePath = readFile "${WORKSPACE}/ Your File Location"                   
               def lines = filePath.readLines() 
               for (line in lines) {                                            
                  build(job: "anotherjob",
                        parameters:[$line]
               } // for
            } // script
         }// steps
      } // stage
   } // stages
} // pipeline
