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（它是开箱即用的默认项目）设置CI / CD管道和发布过程。到目前为止，我没有更改默认代码，也没有添加/删除项目中的任何引用。它在本地构建和运行时没有任何错误。

我创建了一个简单的构建管道，其中包含Restore，Build和Publish等任务。

出于某种原因，发布失败，出现以下错误。

##[section]Starting: Publish

Task         : .NET Core

MSBUILD : error MSB1008: Only one project can be specified.

For switch syntax, type "MSBuild /help"
##[error]Error: C:\Program Files\dotnet\dotnet.exe failed with return code: 1
##[error]Dotnet command failed with non-zero exit code on the following projects : D:\a\1\s\Devops Demo\Devops Demo.csproj
##[section]Finishing: Publish

我用谷歌搜索并建立了几个人抱怨这个错误，但没有任何机构有任何明确的解决方案。

到目前为止，我没有在我的项目和CI / CD配置中尝试任何花哨的东西。以上错误对我来说是一个阻止，因为我无法继续我的简单设置。

如果您有任何建议让我解决此错误，请与我们联系。

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

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

错误是因为在你的--output D:\a\1\a\Devops Demo没有" "并且值包含空格，所以只需将文件夹名称修复为"D:\a\1\a\Devops Demo"。

从.yaml我可以看到你使用变量$(build.artifactstagingdirectory)所以将它改为"$(build.artifactstagingdirectory)"。
