How to setup concurrent build in azure devops service - tfs - tfs

Question

I need to build the code one after another in TFS. When the first build pipeline is completed, the second build pipeline should be triggered automatically

Answer 1

If you are using Azure DevOps service:
You could simply chain related builds together using build completion triggers.
Add a build completion trigger to run your build upon the successful
completion of the triggering build. You can select any other build in
the same project.
After you add a build completion trigger, select the triggering build.
If the triggering build is sourced from a Git repo, you can also
specify branch filters. If you want to use wildcard characters, then
type the branch specification (for example, features/modules/*) and
then press Enter.

If you are using on-premise and your TFS version do not support build completion triggers:
There are two ways to run another build in your current build.
Option 1: add PowerShell task in your current build definition to queue another build by REST API
Assume another build id is 5, so you can add PowerShell task with the script:
$body = #{
definition = #{
id = 5
}
}
$Uri = "http://account.visualstudio.com/DefaultCollection/project/_apis/build/builds?api-version=2.0"
$buildresponse = Invoke-RestMethod -Method Post -UseDefaultCredentials -ContentType application/json -Uri $Uri -Body (ConvertTo-Json $body)
Option 2: install related extension in Market place
There are some extensions you can install for your VSTS account, then you can add the task to queue another build. such as Queue Build(s) Task, Trigger New Build, Queue New Build etc.
