title: While loop to monitor task in gradle
body: <p>I want to monitor a kubernetes pod created after redeploy task and once it is completed, I want to check the liquibase logs. If it is successful, I want to delete the job. How can I achieve this in gradle? I don't want to undeploy immediately after redeploy. So doLast is not an option. The following code doesn't keeps printing ob has not completed yet</p>
  
  <pre><code>task undeployAfterCompleted() {
      group "kubernetes"
      description "Undeploy the liquibase update job after completion"
  
      def output = new ByteArrayOutputStream()
      commandLine "bash", "-c", "kubectl get po -n pbr | grep 'liquibase'  | awk '{ print \$3 }'"
  
      while(!output.toString().equals('Completed')) {
          sleep(5 * 1000)
          println "Job has not completed yet."
          commandLine "bash", "-c", "kubectl get po -n pbr | grep 'liquibase'  | awk '{ print \$3 }'"
      }
  
      tasks.undeploy.execute()
  }
  </code></pre>
