Azure DevOps YAML 管道失败并显示 "A sequence was not expected"

Question

我一直在尝试在 Azure DevOps（版本 Dev17.M153.3）中创建 YAML 管道。

我创建了一个简单的 Hello World C# 控制台应用程序并将其签入我们本地托管的 Azure-Git 存储库。我创建了我的 azure-pipelines.yml 文件并尝试了其中的各种组合，包括：

“.NET 桌面”配置
“入门管道”配置
来自另一个我知道有效的 C# 项目的文件
来自另一个项目的文件，带有各种 mod 以匹配我的测试项目
完全注释掉的文件
一个完全空白的文件

但是，每次尝试构建时，我都会收到以下失败消息：

/azure-pipelines.yml (Line: 1, Col: 1): A sequence was not expected

鉴于错误总是出现在第 1 行并且我在文件中尝试了很多不同的内容，我认为一定是其他配置不正确，而不是 YAML 的问题。

有人知道我做错了什么吗？各种 Google 搜索找到具有类似错误的页面，但 none 的解决方案帮助了我。

*** 编辑以添加各种 YAML 文件尝试：

我目前有一个完全空的 YAML 文件，但仍然收到错误消息。以前的文件包括：

    projects: '.'

您在这里混合了几个管道。

这是一个：


# .NET Desktop
# Build and run tests for .NET Desktop or Windows classic desktop solutions.
# Add steps that publish symbols, save build artifacts, and more:
# [Link removed to avoid odd formatting.]

trigger:
- master

pool:
  name: 'Default'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

steps:
- task: NuGetToolInstaller@0

- task: NuGetCommand@2
  inputs:
    restoreSolution: '$(solution)'

- task: VSBuild@1
  inputs:
    solution: '$(solution)'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: VSTest@2
  inputs:
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: VSBuild@1
  displayName: 'Build solution (debug)'
  inputs:
    solution: '$(solution)'
    vsVersion: 16.0
    platform: x86
    configuration: Debug
    clean: true
  timeoutInMinutes: 10

这里还有一个评论：

# .NET Desktop

# Add steps that publish symbols, save build artifacts, and more:

#    configuration: '$(buildConfiguration)'
#
#- task: VSTest@2
#  inputs:
#    platform: '$(buildPlatform)'
#    configuration: '$(buildConfiguration)'

再一次：


# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml

trigger:
- master

pool:
  vmImage: 'ubuntu-latest'

steps:
- script: echo Hello, world!
  displayName: 'Run a one-line script'

- script: |
    echo Add other tasks to build, test, and deploy your project.
    echo See https://aka.ms/yaml
  displayName: 'Run a multi-line script'

如果您在门户网站上修改管道，您可以使用此按钮进行验证：

如果您的管道一切正常，您将收到反馈。

如果您仍然遇到此问题

从门户中删除您的管道
从存储库中删除您的文件
从门户网站的模板开始
运行它
在门户上根据您的需要进行调整并在保存更改前进行验证
