Visual Studio 在线发布任务自定义条件

Question

我正在尝试使用自定义条件为发布定义设置逻辑。
例如。如果条件等于某些数据运行这一步，否则跳过这一步。
条件是：

eq(variables['Release.Artifacts._XXXXX_.BuildNumber'], 'YYY')

这里_XXXXX_是源别名，YYY是内部版本号。
另外，我尝试了以下方法：

eq(variables['Build.BuildNumber'], 'YYY')

在构建期间使用构建定义中的以下操作设置构建号：（PowerShell 脚本）

Write-Host ("##vso[build.updatebuildnumber]YYY")

但是，发布运行无论如何都会跳过这一步。
检查日志时，我清楚地看到内部版本号等于我的（必需的）数据：

[BUILD_BUILDID] --> [135]
[BUILD_BUILDNUMBER] --> [YYY]
[BUILD_BUILDURI] --> [vstfs:///Build/Build/135]
[BUILD_DEFINITIONID] --> [8]
[BUILD_DEFINITIONNAME] --> [XXXXX]

[BUILD_REPOSITORY_PROVIDER] --> [TfsVersionControl]
[BUILD_REQUESTEDFOR] --> [Sergey]
[BUILD_REQUESTEDFORID] --> [6935e75f-f1d3-434d-9665-536155f280e1]

[RELEASE_ARTIFACTS__XXXXX_DEFINITIONID] --> [8]
[RELEASE_ARTIFACTS__XXXXX_DEFINITIONNAME] --> [XXXXX]
[RELEASE_ARTIFACTS__XXXXX_PROJECTID] --> [1591217f-c442-4ac1-8afd-072c15f20d59]
[RELEASE_ARTIFACTS__XXXXX_PROJECTNAME] --> [XXX Application]
[RELEASE_ARTIFACTS__XXXXX_REPOSITORY_ID] --> [1591217f-c442-4ac1-8afd-072c15f20d59]
[RELEASE_ARTIFACTS__XXXXX_REPOSITORY_NAME] --> [XXX Application]
[RELEASE_ARTIFACTS__XXXXX_REPOSITORY_PROVIDER] --> [TfsVersionControl]

[RELEASE_ARTIFACTS__XXXXX_SOURCEBRANCHNAME] --> [ZZZZ_699]
[RELEASE_ARTIFACTS__XXXXX_SOURCEVERSION] --> [922]
[RELEASE_ARTIFACTS__XXXXX_TYPE] --> [Build]

但是日志显示跳过了步骤（条件）评估：

我遇到了强制转换错误 - 看起来 Release.Artifacts._XXXXX_.BuildNumber 变量未被评估或不存在。

Answer 1

新版本定义（从头开始）运行良好。
Release.Artifacts.{source_alias}.BuildNumber 和 Build.BuildNumber 都可用。

前一个好像是heisenbug之类的。
