Deploying maven artifacts without rebuilding

Question

We are using declarative pipeline, latest Jenkins. Builds are executed in a docker slave container, which has maven and other tools. Our current Jenkinsfile resembles this:

stage('build') { steps { sh 'mvn clean install'} }
stage('test') { /* functional tests using a different tool */ }
stage('publish') { 
    steps {
      // mvn clean deploy -DskipTests -DaltDeploymentRepository... (rebuilds, which we want to avoid, as its a multimodule project)
      // withMaven(options:[artifactsPublisher()] { } ... (from maven-pipeline-plugin)
    }
}

Jenkins classic mode has a Maven Integration plugin which provides a section "Deploy artifacts to Maven repository" which uses Maven RedeployPublisher to only publish artifacts. I am looking for a pipeline equivalent of this, I thought the maven-pipeline-plugin does this, but cant find an example. Any pointers appreciated!

Answer 1

I stumbled upon your question looking for the same thing, and what worked for me was this:

stage('Deploy') {
    sh "'${mvnHome}/bin/mvn' war:war deploy:deploy"
}

Of course, you need to change war:war to the type of the artifact that you want to deploy (so jar:jar or ear:ear). I found this basing on this answer, but it seems to be relevant to maven-war-plugin, as well as to maven-jar-plugin, although there is no forceCreation option in the war goal.
