Help me debug "Fail-no-op: No files were affected in the upload process" when uploading to artifactory

Using Jenkins Ask a question

I have a pipeline that compiles a pom.xml, generates a jar file and uploads it to my local artifactory.

When I try to upload the jar file to artifactory using rtUpload() I am getting this error even though the file exists in my workspace (the build is succssfull and in my workspace the jar is generated).

This is how I have configure my jenkins script:

pipeline {
agent any

environment {
    VERSION = "${env.BUILD_NUMBER}"
    PROJECT_REPO = '****'
    POM_DIR = 'pom.xml'
}

stages {
            stage('Artifactory Configuration') {
        steps {
            rtServer(
                id: 'central',
                url: '***',
                credentialsId: 'jfrog'
            )
        }
            }

    stage('Clone') {
        steps {
            git(
      url: PROJECT_REPO,
      credentialsId: 'git',
      branch: 'master'
  )
        }
    }

    stage('Build') {
        
            steps{
            script {
                
                pom = readMavenPom file: 'pom.xml'
                env.PROJECT_NAME = pom.artifactId
                sh 'mvn -B -DskipTests clean package'
                sh "sed 's/REPLACE_VERSION_HERE/${env.VERSION}/g' upload-pom.xml > upload-pom-${env.VERSION}.xml"
                echo "$WORKSPACE"
                echo "${env.PROJECT_NAME}"
                // zip zipFile: "${env.PROJECT_NAME}-${env.VERSION}-distribution.zip", archive: true, dir: 'dist'
            }
            }
        }
    
    stage('Upload Artifactory') {
        steps {
            rtUpload(
    serverId: 'central',
    
    
        spec: '''{
      "files": [

        }
      ]
}''',


    failNoOp: true,
)
        }
    }
}

post {
        always {
            emailext body: "${currentBuild.currentResult}: Job ${env.JOB_NAME} build ${env.BUILD_NUMBER}\n More info at: ${env.BUILD_URL}",

Thank you in advance.

I think pattern is supposed to be relative to $WORKSPACE. So changing to following should do the trick.

      "pattern": "target/JavaLibraryKoarioMaven-1.2-SNAPSHOT.jar",

or better

      "pattern": "target/JavaLibraryKoarioMaven-*-SNAPSHOT.jar",
