    Description

      Please look at the following comment:

      https://issues.jenkins-ci.org/browse/JENKINS-12827?focusedCommentId=201381&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-201381

      This behavior does not work anymore in Jenkins 1.601.
      The queue item URL which is in the location header of the start-build URL returns HTTP status code 404.

      Steps to reproduce the problem

      Start build via Remote API

      The initial request was:

      http://myjenkins/job/zzz_dummy_a61d370a3954428a949b87fc3d8f3cf8/build

      The HTTP header contains the correct location URL:

      HTTP/1.1 201 Created
      Date: ...
      Server: ...
      Location: http://myjenkins/queue/item/68/
      

      Queue object while build is in the queue

      That works in all used Jenkins versions.
      URL: https://myjenkins:8081/queue/api/json
      JSON response:

      {
          "items": 
      [
      {
          "actions": 
      [
      {
          "causes": 
      [
                  {
                      "shortDescription": "Started by user XYZ",
                      "userId": "xyz",
                      "userName": "xyz"
                  }
              ]
          }
      ],
      "blocked": false,
      "buildable": false,
      "id": 68,
      "inQueueSince": 1425545634280,
      "params": "",
      "stuck": false,
      "task":
                  {
                      "name": "zzz_dummy_a61d370a3954428a949b87fc3d8f3cf8",
                      "url": "https://myjenkins:8081/job/zzz_dummy_a61d370a3954428a949b87fc3d8f3cf8/",
                      "color": "notbuilt"
                  },
                  "url": "queue/item/68/",
                  "why": "In the quiet period. Expires in 4.2 sec",
                  "timestamp": 1425545639280
              }
          ]
      }
      

      Queue item object while build is in the queue

      That does not work anymore in Jenkins 1.601. The following queue item URL is not found (HTTP status code 404).
      URL: https://myjenkins:8081/queue/item/68/api/json
      JSON response:

      {
          "actions": 
      [
      {
          "causes": 
      [
                  {
                      "shortDescription": "Started by user xyz
                      "userId": "xyz",
                      "userName": "xyz"
                  }
              ]
          }
      ],
      "blocked": false,
      "buildable": false,
      "id": 68,
      "inQueueSince": 1425545634280,
      "params": "",
      "stuck": false,
      "task":
      {
          "name": "zzz_dummy_a61d370a3954428a949b87fc3d8f3cf8",
          "url": "https://myjenkins:8081/job/zzz_dummy_a61d370a3954428a949b87fc3d8f3cf8/",
          "color": "blue"
      },
      "url": "queue/item/68/",
      "why": null,
      "cancelled": false,
      "executable":
          {
              "number": 1,
              "url": "https://myjenkins:8081/job/zzz_dummy_a61d370a3954428a949b87fc3d8f3cf8/1/"
          }
      }
      

      Cause of the issue

      The reasons of the problem could be:

      1. The quiet period parameter is ignored. (In our case in it is 5 seconds by default.) That would mean, that queue item is deleted very fast and could not be requested properly.
      2. Maybe the queue item URL is not yet created anymore.

      Possible Solution

      In my opinion the solution would be to make the queue item URL still accessible even if the queue item is deleted. For our build workflow that would be a fine solution.

      Or is there any other way to request finished queue items?

      Goal

      Our goal is to track a Jenkins build via external tools. So if there is another way to safely track a started build, please let me know.
