Azure DevOps 通用包 - 获取从外部源下载的工件版本

Question

我正在寻找一种方法来从外部提要的通用包任务下载的工件中获取版本号。 因为我已经设置下载最新版本versionDownloadExternal : '*'下载后我需要知道下载的版本。

- task: UniversalPackages@0
  displayName: 'Universal download'
  inputs:
  feedsToUse: external
  externalFeedCredentials: '${{ parameters.externalFeedCredentials }}'
  feedDownloadExternal: 'temp-feed'
  packageDownloadExternal: 'temp-artifact'
  downloadDirectory: '$(Pipeline.Workspace)/drop'
  versionDownloadExternal: '*'

查看通用下载任务的日志，我看到版本在那里（1.5.0），但找不到将其保存到变量以便进一步使用的方法。

{"Version":"1.5.0","SuperRootId":"6AAB600ECBE6DF7FAD87B8C49E7B21E32BB1439F410F0A76E41A220630D0847002","ManifestId":"629C9E66D4A57250DD4A430723E6B9338F995133BCFE65D6868BF7E97F1723DA02","Description":"Klevr Portal Build Artifact"}

...

有任何想法吗？ 谢谢。

由于Universal Packages任务没有输出变量，恐怕没有办法直接生成最新版本相关的变量，在下一个任务中使用。

对于解决方法，您可以尝试添加 PowerShell 任务来运行 Rest API： 工件详细信息 - 获取包以获取最新版本。 然后你可以在管道变量中设置它。

下面是一个例子：

$connectionToken="PAT Token"
$base64AuthInfo= [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))

$url = 'https://feeds.dev.azure.com/{Organization}/{Project}/_apis/packaging/Feeds/{Feedname}/Packages/{PackageID}/versions?api-version=6.0-preview.1'

$PackageInfo = (Invoke-RestMethod -Uri $url -Method Get -UseDefaultCredential -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}) 

$LatestVersion= $PackageInfo.value.version | Select-Object -first 1


Write-Host "Latest package Version = $LatestVersion"
echo "##vso[task.setvariable variable=latestversion;isOutput=true]$LatestVersion" 

结果：
