Jenkins run job with stashedfile parameter

Question

I can run a new job from a different job with build job: 'jobname' But my new job also requires a stashed file parameter. Can this be included in the parameters[] ?

Answer 1

Passing the parameter as a io.jenkins.plugins.file_parameters.StashedFileParameterValue worked for me. StashedFileParameterValue requires a org.apache.commons.fileupload.FileItem which also needs to be created. Also FileItem is not serializable, so it needs to be created in a @NonCPS method. Combining all of that together, a simple pipeline that calls a job, stashed-file, which has a stashedFile parameter named INPUT_FILE, looks like below:

@NonCPS
void triggerStashedFileJob(File testFile) {
    def factory = new org.apache.commons.fileupload.disk.DiskFileItemFactory()
    def fileItem = factory.createItem('file', 'text/plain', false, 'test-copy.txt')
    fileItem.outputStream << testFile.bytes

    build job: 'stashed-file', parameters: [
        new io.jenkins.plugins.file_parameters.StashedFileParameterValue('INPUT_FILE', fileItem),
    ]
}

pipeline {
    agent any

    stages {
        stage('trigger job that needs stashed file') {
            steps {
                deleteDir() // To cleanup workspace 
                sh '''
                   echo "hello from parent job" >> test.txt
                '''

                script {
                    File testFile = new File("${env.WORKSPACE}/test.txt")
                    triggerStashedFileJob(testFile)
                }
            }
        }
    }
}
