title: No drop information in build.complete webhook payload on Azure DevOps
body: <p>I created an Azure DevOps webhook for build.complete event and i'd like to get information about artifacts that have been published from the build but the resource.drop information is always null:</p>
  
  <pre><code>"resource": {
  "uri": "vstfs:///Build/Build/10301",
  "id": 10301,
  "buildNumber": "cxcxzccxczxcxzcx_master_2018-12-17.3",
  "url": "https://xxxxxxxxxxxxxxxxxx/_apis/build/Builds/10301",
  "startTime": "2018-12-17T15:19:29.3762035Z",
  "finishTime": "2018-12-17T15:22:01.4107196Z",
  "reason": "batchedCI",
  "status": "succeeded",
  "drop": {},
  "log": {},
  </code></pre>
  
  <p>I'm using the Publish Build Artifacts v.1 task to publish the artifact.  The artifact publish location is Azure Pipelines/TFS.  Is there something i should add to the build definition to get the information about the artifacts in the webhook payload?</p>
  
  <p>Thanks!</p>
