Azure DevOps - YAML Pipeline with multiple jobs syntax error

Question

I've got a YAML pipeline that is attempting to run multiple jobs, but I'm getting a syntax error for the first task (the GitVesion command-line task), which I don't get in other pipelines that I've that have a single job.

The error I get is:

(Line: 29, Col: 18, Idx: 576) - (Line: 29, Col: 18, Idx: 576): Mapping values are not allowed in this context.

Line 29 is the displayName of the first task (actual pipeline has comments at top of the file that have been removed below).

Answer 1

You have 3 issues:

1. The displayName should be aligned with the task.
2. The keys after the inputs should be in right to inputs and not aligned.
3. The job names couldn't be with spaces.

I fixed it for you, this is correct:

Answer 2

I believe your displayName key(s) should be aligned with the first character of your task key(s) ala:

- job: Backend
  steps:
  - task: CmdLine@1
    displayName: GitVersion
    inputs:
    filename: '$(GitVersionPath)'
    arguments: '$(GitVersionArguments)'

  - task: DeleteFiles@1
    displayName: 'Delete files from $(Build.ArtifactStagingDirectory)'
    inputs:
    SourceFolder: '$(Build.ArtifactStagingDirectory)'
    Contents: '**/Naus*.nupkg'
