title: Jenkins pipeline with maven, The specified global settings file does not exist
body: <p>I have a jenkins pipeline job, that is depending on simple Jenkinsfile instructions:</p>
  
  <pre><code>pipeline {
      agent any
      stages {
          stage('Install Dep') {
              steps {
                    sh 'ls'
            configFileProvider([configFile(fileId: '3fada107-8341-40ec-b1b6-d49e48479157', variable: 'SETTINGS')]) {
            sh 'ls'
            sh 'mvn -gs SETTINGS install'
          }
        }
          }
      }
  }
  </code></pre>
  
  <p>When i'm trying to build, i got the following Error: </p>
  
  <pre><code>+ mvn -gs SETTINGS install
  [ERROR] Error executing Maven.
  [ERROR] The specified global settings file does not exist: /home/jenkins/workspace/FBPMCB2/SETTINGS
  </code></pre>
  
  <p>I'm using Config File Management plugin to define the settings.xml file, and it's defined but i'm not sure why i'm still getting this error, advise please?</p>
