我正在寻找一种方法，从使用通用包任务从外部源下载的工件中获取版本号。因为我已设置在下载后使用 versionDownloadExternal : '*' 下载最新版本，所以我需要知道下载的是哪个版本。
- 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，我发现该版本已存在(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"}

...
有什么想法吗？谢谢。
最佳答案
由于Universal Packages任务没有输出变量，恐怕没办法直接生成最新版本相关的变量并在下一个任务中使用。
要解决此问题，您可以尝试添加 PowerShell 任务来运行 Rest API:Artifact Details - Get Package获取最新版本。然后您可以将其设置在管道变量中。
这是一个例子:
$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:
