How to deploy multiple artifacts to nexus?

Please find the below syntax for the nexusArtifactUploader in Jenkinsfile.

nexusArtifactUploader artifacts: [   [artifactId: 'nexus-artifact-uploader', classifier: 'debug', file: 'nexus-artifact-uploader.jar', type: 'jar'],    [artifactId: 'nexus-artifact-uploader', classifier: 'debug', file: 'nexus-artifact-uploader.hpi', type: 'hpi']], credentialsId: '44620c50-1589-4617-a677-7563985e46e1', groupId: 'sp.sd', nexusUrl: 'localhost:8080/nexus', nexusVersion: 'nexus2', protocol: 'http', repository: 'NexusArtifactUploader', version: '2.4'

You can generate the above syntax from the pipeline snippet generator.

In my case there was a problem with deploying ${artifactName}.jar and ${artifactName}-sources.jar artifacts to the same Nexus directory using Nexus Jenkins Plugin.

The problem was with the same packaging type (jar), that's why these artifacts couldn't be uploaded to Nexus: plugin changes both provided file names to ${artifactId}-${version}.${packaging} and I've got the error:

Upload component was unsuccessful (400 response from server)

Fixed the issue by providing classifier for -sources.jar artifact:

stage('Publish') {    def pom = readMavenPom file: 'pom.xml'    nexusPublisher nexusInstanceId: 'your-nexus-instance-id', \        nexusRepositoryId: 'your-nexus-repository-id', \        packages: [[$class: 'MavenPackage', \        mavenAssetList: [[classifier: '', extension: '', filePath: "target/${pom.artifactId}-${pom.version}.${pom.packaging}"], \                         [classifier: 'sources', extension: '', filePath: "target/${pom.artifactId}-${pom.version}-sources.${pom.packaging}"]], \        mavenCoordinate: [artifactId: "${pom.artifactId}", \        groupId: "${pom.groupId}", \        packaging: "${pom.packaging}", \        version: "${pom.version}-${env.BUILD_NUMBER}"]]]}
