如何使用 Azure DevOps 发布？

Question

我正在尝试使用 Azure DevOps 为 .NET Core 2.1 示例项目（即开箱即用的默认项目）设置 CI/CD 管道和发布流程。到目前为止，我还没有更改默认代码，也没有在项目中添加/删除任何引用。它正在本地构建和运行，没有任何错误。

我创建了一个简单的构建管道，其中包含还原、构建和发布等任务。

由于某种原因，发布失败并出现以下错误。

##[section]Starting: Publish

For switch syntax, type "MSBuild /help"

我在谷歌上搜索并找到了几个抱怨这个错误的人，但没有人有任何明确的解决方案。

到目前为止，我还没有在我的项目和 CI/CD 配置中尝试过任何花哨的东西。上述错误对我来说是一个障碍，因为我无法继续进行简单的 devops 设置。

如果您对我修复此错误有任何建议，请告诉我。

我的 YAML 如下，

pool:
  name: Hosted VS2017
#Your build pipeline references an undefined variable named ‘Parameters.RestoreBuildProjects’. Create or edit the build pipeline for this YAML file, define the variable on the Variables tab. See https://go.microsoft.com/fwlink/?linkid=865972

#Your build pipeline references the ‘BuildConfiguration’ variable, which you’ve selected to be settable at queue time. Create or edit the build pipeline for this YAML file, define the variable on the Variables tab, and then select the option to make it settable at queue time.

steps:
- task: DotNetCoreCLI@2
  displayName: Restore
  inputs:
    command: restore
    projects: '$(Parameters.RestoreBuildProjects)'

- task: DotNetCoreCLI@2
  displayName: Build
  inputs:
    projects: '$(Parameters.RestoreBuildProjects)'
    arguments: '--configuration $(BuildConfiguration)'

- task: DotNetCoreCLI@2
  displayName: Publish
  inputs:
    command: publish
    publishWebProjects: True
    arguments: '--configuration $(BuildConfiguration) --output $(build.artifactstagingdirectory)'
    workingDirectory: 'Devops Demo'

- task: PublishBuildArtifacts@1
  displayName: 'Publish Artifact'
  inputs:
    PathtoPublish: '$(build.artifactstagingdirectory)'

Answer 1

错误是因为在您的--output D:\a\1\a\Devops Demo 中没有" " 并且值包含空格，所以只需将文件夹名称固定为"D:\a\1\a\Devops Demo"。

从.yaml 我可以看到您使用变量$(build.artifactstagingdirectory)，因此将其更改为"$(build.artifactstagingdirectory)"。
