Azure devops 如何获取拾取列表中的最新值

我正在尝试为Azure DevOps开发一个用于发布门的扩展/管道任务。不了解如何将最新值绑定到拾取列表，如下所示：

每次生成完成时，拾取列表都应将最新的生成Id作为所选值

这是我试过的代码片段， 这将创建一个拾取列表

{
  "name": "buildId",
  "type": "pickList",
  "label": "Artifact",
  "required": true,
  "defaultValue": "Latest",
  "properties": {
    "DisableManageLink": "True",
    "EditableOptions": "True"
  }
  "helpMarkDown": "Build Artifacts"
},

这将绑定picklist的值

{
  "target": "buildId",
  "endpointId": "tfs:teamfoundation",
  "endpointUrl": "{{endpoint.url}}/{{system.teamProject}}/_apis/build/builds?api-version=5.0",
  "resultSelector": "jsonpath:$.value[*]",
  "resultTemplate": "{ \"Value\" : \"{{{id}}}\", \"DisplayValue\" : \"{{{buildNumber}}} \" }"
}

---

请告诉我是否有任何方法可以实现此功能。

恐怕您需要实现自己的代码方法，以将

最新的

值绑定到最新的buildid

例如在。根据字段

buildVersionToDownload

的选定值（即最新版本）检索最新版本id：请参见以下内容：

buildVersionDownload

有三个选项

  {
                "name": "buildVersionToDownload",
                "type": "pickList",
                "label": "Build version to download",
                "defaultValue": "latest",
                "visibleRule": "buildType == specific",
                "required": true,
                "options": {
                    "latest": "Latest",
                    "latestFromBranch": "Latest from specific branch and specified Build Tags",
                    "specific": "Specific version"
                }
            }

如果将

buildVersionDownload

值选择为

specific

。然后需要在

build

picklist中选择构建id

{
            "name": "buildId",
            "type": "pickList",
            "label": "Build",
            "defaultValue": "",
            "required": true,
            "visibleRule": "buildType == specific && buildVersionToDownload == specific",
            "properties": {
                "EditableOptions": "True",
                "DisableManageLink": "True"
            },
            "helpMarkDown": "The build from which to download the artifacts"
        }

buildVersionDownload

未绑定到数据源，仅绑定了

buildId

：

{
            "endpointId": "tfs:teamfoundation",
            "target": "buildId",
            "endpointUrl": "{{endpoint.url}}/{{project}}/_apis/build/builds?definitions={{definition}}&resultFilter=succeeded,partiallySucceeded&$top=200",
            "resultSelector": "jsonpath:$.value[*]",
            "parameters": {
                "project": "$(project)",
                "definition": "$(definition)"
            },
            "resultTemplate": "{ \"Value\" : \"{{{id}}}\", \"DisplayValue\" : \"{{{buildNumber}}}\" }"
        }

如果选择

buildVersionDownload

作为

latest

。然后通过代码检索最新的构建id。参见代码示例

因此，在您的自定义任务中。当

默认版本

为

最新版本

时。您可以在代码方法中获取最新的生成id。当

默认版本

不是

最新版本

时。然后使

工件可见，以从选取列表中选择构建id

{
            "name": "buildId",
            "type": "pickList",
            "label": "Build",
            "defaultValue": "",
            "required": true,
            "visibleRule": "buildType == specific && buildVersionToDownload == specific",
            "properties": {
                "EditableOptions": "True",
                "DisableManageLink": "True"
            },
            "helpMarkDown": "The build from which to download the artifacts"
        }
