How can I delete an Azure DevOps build definition that it claims is retained by a release? - azure-devops

Question

I'm trying to delete an Azure DevOps build definition but it won't let me since it says:
"One or more builds associated with the requested pipeline(s) are retained by a release. The pipeline(s) and builds will not be deleted."
However there's no obvious way to see what release is causing a build to be retained. I tried searching online, of course, but all the examples/screenshots of how to do this in the web UI are showing UI from several iterations ago of the Azure DevOps website so none of the controls look the same anymore. I don't see a lock icon anywhere, for example.
How can I find the releases that are holding onto these build definitions so I can delete them and then delete the build definition?
Thanks!

Answer 1

When you open the build pipeline to see its detailed build records, you can see the relevant release name and its link:
On old pipeline version, there had a lock icon which can obvious let us know it is retained. In fact, the lock icon not only means it is retained by release, manual build retain also show this icon. But, seems we missed this obvious icon while we expand the new sprint.
As a workaround to get list of builds which retained by release, here has a short script can help you achieve by using Rest api:
$token = "{PAT token}"
$url ="https://dev.azure.com/{org name}/{project name}/_apis/build/builds?api-version=5.1"
$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($token)"))
$response = Invoke-RestMethod -Uri $url -Headers #{Authorization = "Basic $token"} -Method Get
$results = $response.value | Where {$_.retainedByRelease -eq "true"} #|
Write-Host "results = $($results.id | ConvertTo-Json -Depth 100)"
First, use list builds api to get all builds that in current project. Then for the builds which retained by release, since there has a parameter can indicate it: retainedByRelease here I use $_.retainedByRelease -eq "true" to get the builds list which actual retained by release:
The above script is very universal, can be used in Powershell-ise and Powershell Command Line and the Powershell task of VSTS without change anything.
Update in 11/19:
Based on #Auth's comment, if want to get its associated release, the most easiest way is find the build, and then check its associate release pipeline as the screenshot shown I shared above.
If this does not satisfied what you want, and the previous API we used does not include any releases info in that, so here, you need use this API: Releases - Get Release:
GET https://vsrm.dev.azure.com/{org name}/{project name}/_apis/release/releases?sourceId={project id}:{build definition id}&api-version=5.1
In this API, you need specified the project id:build definition id to filter releases.
With the icon missing, will let the corresponding team know and try to add it in the future sprint.

I have had this issue when some one delete a repository that was associated with a "POC" pipeline. I was not able to delete the pipeline.
When I tried to delete the pipeline, I got following message:
One or more builds associated with the requested pipeline(s) are retained by a release. The pipeline(s) and builds will not be deleted.
I did following steps to delete the pipeline:
My Goal was to delete PublishBuildArtifacts-Infrastructure pipeline as shown in image. So I clicked on the pipeline.
I see list of Builds (Runs) that is associated with my pipeline. I click on the 3 dots and click on View Retention Lease.
Then I click Remove all.
Now you can delete your build.
Repeat steps 2-4 for each run. When you have delete all builds, now you can delete the pipeline by clicking on the 3 dot menu, as shown in the image below.
Enjoy!
