Cannot use readMavenPom in Jenkinsfile

Question

I am working on a Jenkinsfile for use with Jenkins 2.0. The readMavenPom method is not recognized. Is there some configuration I am missing to make this available?

My Jenkinsfile:

node {
  stage 'Checkout'
  checkout scm
  env.PATH = "${tool 'maven-3'}/bin:${env.PATH}"
  stage 'Build'
  def pom = readMavenPom file: 'pom.xml'
  echo "${pom}"
  sh "mvn -DskipTests=true verify"
}

When run, I get the following error:

java.lang.NoSuchMethodError: No such DSL method 'readMavenPom' found among

Answer 1

I needed to install the pipeline-utility-steps plugin.

Before you use this step, note the below from writeMavenPom/readMavenPom documentation:

Avoid using this step and readMavenPom. It is better to use the sh step to run mvn goals

(I found) Maybe because of github.com/jenkinsci/pipeline-utility-steps-plugin/pull/47 – Limnetic

1. Use below command to read whole pom.xml in declarative pipeline :

    sh  ‘mvn -f  ./path-to-my-service/pom.xml help:evaluate -Dexpression=project -q -DforceStdout’
   

2. For specific property in a pom.xml use same command with tag hierarchy :
   project.property.sub-property........and so on

      def pom_version = sh script: 'mvn -f ./path-to-my-service/pom.xml -DskipTests help:evaluate -Dexpression=project.version -q -DforceStdout', returnStdout: true;
   
      def pom_artifactId = sh script: 'mvn -f ./path-to-my-service/pom.xml -DskipTests help: evaluate -Dexpression=project.artifactId -q -DforceStdout', returnStdout: true;
   
      def pom_groupId = sh script: 'mvn -f ./path-to-my-service/pom.xml -DskipTests help:evaluate -Dexpression=project.groupId -q -DforceStdout', returnStdout: true;
