title: Artifactory Configuration in Jenkins Pipeline Job
body: <p>I am trying to configure the Artifactory in Jenkins Pipeline Job. I am referring to JFROG documentation for the same which mentions 3 ways to instantiate artifactory object:</p>
  
  <pre><code>def server = Artifactory.server 'my-server-id'
  def server = Artifactory.newServer url: 'artifactory-url', username: 'username', password: 'password'
  def server = Artifactory.newServer url: 'artifactory-url', credentialsId: 'ccrreeddeennttiiaall'
  </code></pre>
  
  <p>We can use any of the above ways and after getting the <code>buildInfo</code> which we want to publish in artifactory we do </p>
  
  <pre><code>server.publishBuildInfo buildInfo
  </code></pre>
  
  <p>This step is causing exception for whci th stacktrace below- </p>
  
  <pre><code>java.lang.NullPointerException

  <p>UPDATE 1:</p>
  
  <pre><code>node {
  def server = Artifactory.newServer url: SERVER_URL, credentialsId: CREDENTIALS
  def rtMaven = Artifactory.newMavenBuild()
  
  stage 'Build'
      git url: 'https://github.com/jfrogdev/project-examples.git'
  
  stage 'Artifactory configuration'
      rtMaven.tool = MAVEN_TOOL // Tool name from Jenkins configuration
      rtMaven.deployer releaseRepo:'libs-release-local', snapshotRepo:'libs-snapshot-local', server: server
      rtMaven.resolver releaseRepo:'libs-release', snapshotRepo:'libs-snapshot', server: server
      def buildInfo = Artifactory.newBuildInfo()
  
  stage 'Publish build info'
      server.publishBuildInfo buildInfo}
  </code></pre>
  
  <p><code>NullPointerException</code> is caused by the last statement <code>server.publishbuildInfo buildInfo</code>. So i think i am not getting the Artifactory Server Instance.</p>
  
  <p>UPDATE 2:</p>
  
  <p>I was able to resolve the above issues by passing the correct credentials. But now when i am trying to deploy the artifacts to Artifactory repository then getting the following exception:</p>
