Pass content from build back into Visual Studio Team Services Build

I am running build on Azure with a custom build agent (using Unity3d to be precise) I generate output of the build within a .txt file on the build machine and would like to include content within work items created during build.

Example:

  1. Unity build fails and an error is logged to Build.log.
  2. New bug is created with reference to build and the error message from the logfile

Right now I am using a powershell script

$content = [IO.File]::ReadAllText("$(Build.Repository.LocalPath)\BuildProjectPC\Build.log")
Write-Host "##vso[task.setvariable variable=logContent;]$content"

To format the bug i use System.Description = $logContent but the content of the variable from PS does for some reason not end up in the bug item (it just contains "$logContent").

Any idea or direction how to fix this, respectively how to feed info back into vsts?

The variable value that used for creating work item is initialized before running build steps, so you can’t specify a dynamic variable or change the variable value during the build step that used for creating work item. You can follow up these steps to verify it:

  1. Open your build definition > Variable > Add a new variable (e.g. logContent, value: oldValue)
  2. Select Options > Check Work Item on Failure > Additional Fields > System.Title $(logContent)
  3. Add PowerShell build step: Write-Host "$(logContent)"
  4. Add PowerShell build step: Write-Host "##vso[task.setvariable variable=logContent;]newValue"
  5. Add PowerShell build step: Write-Host "$(logContent)"
  6. Add PowerShell build step: [Environment]::Exit(1)

The log result:

  1. Step 3 output oldValue
  2. Step 5 output newValue
  3. The created work item title oldValue.

The workaround for your requirement is that, you can create a work item and associated to build through PowerShell with Rest API (add PowerShell step at the end of other steps and Check Always run option).

Associate work item to build:

Request Type: Patch

Request URL: https://[your vsts account].visualstudio.com/DefaultCollection/_apis/wit/workitems/[work item id]?api-version=1.0

Content-Type:application/json-patch+json

Body:

[
  {
    "op": "add",
    "path": "/relations/-",
    "value": {
      "rel": "ArtifactLink",
      "url": "vstfs:///Build/Build/[build id]",
      "attributes": {
        "comment": "Making a new link for the dependency"
      }
    }
  }
]

You can refer to this blog for PowerShell scripts to create and associate work item.

In the Additional Fields you need to reference the build/release definition variable with the following notation: $(logContent)

as shown here below:
