title: Jenkins Build error - groovy.lang.MissingPropertyException: No such property: fileLoader for class: groovy.lang.Binding
body: <p><strong>Objective:</strong>
  we have a file in our application folder named as JenkinsFile. From that File, we are trying to call a groovy script file which contains the pipeline script of Jenkins build and deploy. The groovy script file is in seperate GITLAB repository.</p>
  
  <p><strong>Jenkins file code:</strong></p>
  
  <pre><code>#!groovy
  @Library("usingALibrary") _
  
  def COMMON_REPO       = 'GITLAB_URL'
  def REDIRECTED_SCRIPT = 'buildJenkinsPipelineScript.groovy'
  def CREDENTIALS_ID    = 'credentials'
  
  def jenkinsFile
  jenkinsFile = fileLoader.fromGit(REDIRECTED_SCRIPT, COMMON_REPO, 'master', CREDENTIALS_ID, 'maven')
  try{
      jenkinsFile.start()
  }
  catch(NullPointerException e)
  {
      echo "Script threw a NullPointerException but it will be omitted."
  }
