Azure DevOps pipeline release Error: No package found with specified pattern: D:a 1a***.zip

Question

I have an ASP.NET Core project in Azure DevOps repository and it gets built OK using the DevOps build pipeline. However, the release over that builds always fails with this error:

Error: No package found with specified pattern: D:a 1a***.zip

I've already checked out this and this Q/As, but cannot figure out the solution.

Here is my azure.pipelines.yml file:

pool:
  vmImage: 'vs2017-win2016'

variables:
  buildConfiguration: 'Release'

steps:
  - script: dotnet build ".srcMyProject.sln" --configuration $(buildConfiguration)
    displayName: 'dotnet build $(buildConfiguration)'
  - script: dotnet publish ".srcMyProject.sln" --configuration $(buildConfiguration) --output $(Build.ArtifactStagingDirectory)
     displayName: 'dotnet publish $(buildConfiguration)'
  - task: PublishBuildArtifacts@1
    pathtoPublish: '$(Build.ArtifactStagingDirectory)' 
    artifactName: 'drop' 
    publishLocation: 'Container'

Answer 1

I had the same problem and after googling around I found this answer

In summary, that answer says that you you need to go to your builds section and edit it.

At the very end of the .yaml file you need to add an additional line.

"- task: PublishBuildArtifacts@1"

Queue a new build and you should be good to go!
