    Description

      Expected behavior:

      In pipeline:

       

      withMaven(
       maven: mvnId, // Maven installation declared in the Jenkins "Global Tool Configuration"
       mavenSettingsConfig: mvnSettingsId, // Maven settings.xml file defined with the Jenkins Config File Provider Plugin
       mavenLocalRepo: mavenLocalRepo
       )
      { 
         result = sh( 
            returnStdout: true, 
            script: 'mvn org.apache.maven.plugins:maven-help-plugin::evaluate -Dexpression=project.version -q -DforceStdout -B" ) 
      }
      

       

      Desired result variable value:

      1.5.0

       

      Actual result variable:

      ----- withMaven Wrapper script -----
       Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-24T19:49:05Z)
       Maven home: /var/lib/jenkins/tools/hudson.tasks.Maven_MavenInstallation/mvn-3.5.3
       Java version: 1.8.0_161, vendor: Oracle Corporation
       Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.161-0.b14.el7_4.x86_64/jre
       Default locale: en_US, platform encoding: UTF-8
       OS name: "linux", version: "3.10.0-693.17.1.el7.x86_64", arch: "amd64", family: "unix"
       1.5.0

      Analysis:

      withMaven wrapper adds stdout info, that cannot be removed, disabled, according to source:

      https://github.com/jenkinsci/pipeline-maven-plugin/blob/b150161c91769de782af6c5b2ebe7907a4bd17b0/jenkins-plugin/src/main/java/org/jenkinsci/plugins/pipeline/maven/WithMavenStepExecution2.java

      However, that breaks the way we gets output with mvn command.

      Workaround: specifically to maven-help-plugin, I can redirect output to a file, and readFile that.

      Long-term solution (exclusive choice):

      1. add a silent field to withMaven, to disable any output?
      2. add a showDebug field to show debug info
      3. do not show debug info, except when mvn command fails

      Thank you.
