I'm trying to create a release pipeline with PR trigger. I saw in every documentation, that there should be a "Pull Request trigger" toggle in the artifact like here:
However when I click the Continuous deployment trigger icon, there is no Pull request trigger:
I don't know what I'm doing wrong, I followed every step from Microsoft's documentation.
On stage triggers it shows the PR trigger option with a warning:
I created multiple new pipelines, the toggle just doesn't show up. The artifact is built from code on Github
This situation may be if you are using Team Foundation Version Control for your builds:
TFVC does not support pull requests. Please, verify you are trying to use GIT in your build pipeline:
To ensure the uniqueness of every artifact download, each artifact source linked to a release pipeline is automatically provided with a specific download location known as the source alias. Please see the official doc for more details: Artifact source alias
I notice:
1.The original build name own ''.
2.Your source alias without the download location ''.
if I change the source alias by cutting the '_', chances are not seeing the pull request trigger part. It's not related to repo location, repo type when you choose build type artifact.
The workaround is:
If your artifact source alias name doesn't have ''or'-', then you could cut the system added ''.
If you do want cut the system added '', please don't add '' in artifact source alias name.
For your reference, if you want to change artifact source alias name, you can change the name of the build pipeline.
I hope this could do some help.

I have a continuously triggered Azure DevOps release definition that deploys a compiled Angular app to a web server and also runs Cypress e2e tests. The Cypress tests must run against the source code, so that means I need an artifact that is able to reference the same commit that was used to create the compiled app.
I created a GitHub artifact that gets the source code, but I can't figure out how to automatically change the branch/commit to whatever was used for the compiled app (it could be any branch and the names are not known ahead of time). Azure forces me to enter a hard-coded branch name and it does not accept wildcards or variables.
If I could simply use the variable ${Release.Artifacts.{alias}.SourceBranchName} for the default branch, I think I'd achieve my goal. Since Azure doesn't allow this, is there an alternative approach that accomplishes the same thing?
Note 1: The "Default version" dropdown has an option "Specify at the time of release creation", but that is intended for manual releases and can't be used for triggered ones, so no luck there.
Note 2: I looked into publishing the source code as an artifact, but it currently has almost 70,000 files and it adds more than an hour to the build step, so that also is not an option.
When you use the Release Pipeline artifacts, you are not able to set the pipeline variable in the Default branch field. This field only supports hard-coded.
is there an alternative approach that accomplishes the same thing?
The variable:$(Release.Artifacts.{alias}.SourceBranchName) can be used in the Release Pipeline agent job.
Workaround:
You can remove the Github artifacts and then add a Command Line task/PowerShell task/ Bash task to run the git command to clone the target repo.
For example:
git clone -b $(Release.Artifacts.{alias}.SourceBranchName) GithubRepoURL
PowerShell sample:
In this case, the script will use the same branch as Build Artifacts to checkout the source code.
I checked several sources, seems possible, but can't get it work.
What I want is that whenever a PR is created and PR build is successful, then a PR release is run and a site is created (either with PR Id or PR source branch, e.g. pr122--xxx.azuresite.net).
From an answer for this question,
Looks like I could use release.artifacts.alias.PULLREQUEST.ID, but when I tried it, this doesn't work at all. Also from the official doc, there is no mention of this variable. Is this only for the new YAML pipeline?
As most of our things are in classic pipeline, the solution I can think of is to parse the build source, which is refs/pull/11201/merge. Looks like 11201 is the Pull Request ID, so I just need to replace refs, pull,merge and "/". But I am not sure if better approaches available.
Following this doc: Deploy pull request Artifacts with Azure Pipelines, we can successfully create a pull request deployment by choosing Azure Repos as the source artifact.
If one pull request is created, a new release will be triggered. And as you have found, the source branch of build source is "refs/pull/{PullRequestId}/merge", so you are right.
In addition, if you set the Azure Repos as the primary artifact, we can get the pull request branch by using the predefined variable Release.Artifacts.{alias}.SourceBranch. In below example, we can use the PowerShell task to run below command.
Write-Host "Release.Artifacts._215.SourceBranch: $(Release.Artifacts._215.SourceBranch)
See: Default variables - General Artifact for details.
Is there a way I can set up a build in Azure DevOps to automatically run every time a PR is merged and completed and contains a specific keyword in the name? for example: "Some PR name here [RUN_BUILD_123]"
Edit:
The reason for this is because I have different builds on top of the same branch so instead of triggering all the builds I just want to trigger those that I know need to be rebuilt based on the particular projects getting changed.
A PR has a target-branch. If you want to trigger a build after a PR is completed just configure a build with a ci-trigger for that target-branch. You can't check for certain keywords in the PR-name unfortunately
Agree with D.J. For detailed setting, you can check the Enable continous intergration option in the Triggers settings, then select the target branch you want ci-trigger build in the Branch filters.This will automatically trigger the build after pr is completed.
But you can't do it if you want to include special keywords in pr name.
Topic is a bit old, but if there is anyone who want's to archive this stumbling over this topic - here is my approach how I would solve this:
The basic of all are scripted pipelines, so if you still do it in the GUI - that's wasted time. Create a .yml build and put it into your Git. The M$ documentation is really helpful with this.
Create the trigger for your branch
Put this on the first line, so the pipeline will be executed when master (or your branch) has a new commit
trigger:
branches:
include:
- master
Read out the commit message via the VSTS variables
Trigger the builds, based on their ID via REST API (you can use the pipeline token for authentication)
I have branch validation in the form of a PR Build, which means I have duplicated my original build and removed some steps (such as pushing to my docker registry).
I would prefer to simply be able to automatically add a tag / some kind of identifier to a PR build and exclude the step on the original build using custom conditions.
Does anyone know if this is possible, and if so how to achieve it? I'd really rather not duplicate each and every build.
If I understand your question correctly, you would like to run a build step based on a custom condition. In this case, the custom condition is whether the build is a PR build or not.
You can check the pre-defined build variables available in Azure Devops here and you can see that there is a Build.Reason variable.
I am listing a few variables here.
Manual: A user manually queued the build.
IndividualCI: Continuous integration (CI) triggered by a Git push or a TFVC check-in.
PullRequest: The build was triggered by a Git branch policy that requires a build.
You can specify the condition in custom condition settings of your build step like this.
More examples available in the docs
I currently have a release defined for pushing clients to an internal nuget server.
Each release is identical in terms of steps, the only thing that changes is the triggering artifact.
However when I add another artifact to a "generic" release, so that there are now ClientA and ClientB artifacts on the release, both artifacts are downloaded when the release is triggered and they are both then pushed.
What I would like to know is if it is possible to have the release only download the triggering artifact.
Example:
A release is triggered on both ClientA and ClientB.
ClientB is released. The build triggers and only uses the ClientB artifact during the deployment.
I don't think this is possible at the moment, but something similar is possible though.
Create a task group from the current release definition as described here: https://learn.microsoft.com/en-us/vsts/pipelines/library/task-groups?view=vsts
There clone the release definition and change the artifact from ClientA to ClientB.
You'll end up having two release definition, both sharing the steps but the artifacts will be different.
EDIT: PowerShell script to download Build artifacts
Eddie suggested a nice workaround. Here's how you can pull down an artifact manually.
You need to enable Allow scripts to access OAuth token
Add a PowerShell task to each phase and reference the DownloadBuildArtifacts.ps1 script
If the release is triggered by build artifacts, the value of the pre-defined variable "$(RELEASE.TRIGGERINGARTIFACT.ALIAS)" will be the triggered artifacts alias. You can get the value of this variable to determine which artifact trigger the release.
There isn't any way to achieve this out of box. But you can disable auto download artifacts and add a powershell script in your release definition to get the triggered artifact and download it.
There isn't the way to just download the triggered artifacts, but you can identify which artifact trigger this release through RELEASE_TRIGGERINGARTIFACT_ALIAS variable.
So, you can push corresponding one per to that variable.
