[FIXED] Jenkins and Maven - empty package - how to define what should be packaged?

Issue

I defined a Jenkins job to build my code. I get an JAR output but with empty content. How I should define what folder should be pakcaged? Code which I got from developers is mostly AngularJS scripts along with some npm packages which are being installed and used for npm build. After that I need to create maven package and upload it to JFROG Artifactory. After the npm install and npm build I am getting new folder dist and its subfolder arena-web-ruf needs to be packaged as a result of Jenkins build.

So the folder that needs to be packaged from the current folder where Jenkins is triggered is: ./dist/apps/arena-web-ruf/ How does maven knows that it should pick that folder? I tried to zip manually that folder and unzip it in the current dir with same name arena-web-ruf but I got empty JAR.

pom.xml definition:

<modelVersion>4.0.0</modelVersion>
<groupId>iprods</groupId>
<artifactId>arena-web-ruf</artifactId>
<version>2022.3-SNAPSHOT</version>

Jenkins build definition:

        steps {
            rtServer (
                id: 'Artifactory',
                url: 'https://artifactory.domain.dev/artifactory',
                credentialsId: 'ac0c0e829676'
            )

            rtMavenDeployer (
            id: "MAVEN_DEPLOYER",
            serverId: "Artifactory",
            releaseRepo: "my-generic-release-local",
            snapshotRepo: "my-generic-snapshot-local"
            )

            rtMavenResolver (
                id: "MAVEN_RESOLVER",
                serverId: "Artifactory",
                releaseRepo: "apache-maven-remote",
                snapshotRepo: "apache-maven-remote"
            )
        }

............................................................

        steps {
            rtMavenRun (
                tool: "maven-3.2.5", // Tool name from Jenkins configuration
                pom: 'pom.xml',
                goals: 'clean install',
                deployerId: "MAVEN_DEPLOYER",
                resolverId: "MAVEN_RESOLVER"
            )
        }

Solution

As discussed in the chat, and assuming you have a pom file to upload alongside the zip, you can do something like this:

spec: """{
    "files": [
        {
            "pattern": "arena-web/arena.zip",
            "target": "myrepo/the/group/arena-web/1.0.0-SNAPSHOT/arena-web-1.0.0-SNAPSHOT.zip"
        },
        {
            "pattern": "wherever/is/pom.xml",
            "target": "myrepo/the/group/arena-web/1.0.0-SNAPSHOT/arena-web-1.0.0-SNAPSHOT.pom"
        }
    ]
}"""
