##[错误]未找到与指定模式匹配的项目文件

Question

我在构建管道时遇到问题。

代理池托管于 VS2017

YAML 是

pool:
  vmImage: 'VS2017-Win2016'

variables:
  buildConfiguration: 'Debug'

steps:
- task: DotNetCoreInstaller@0
  displayName: 'Use .NET Core sdk 2.1.5'
  inputs:
    version: 2.1.403


- task: DotNetCoreCLI@2
  displayName: Restore
  inputs:
    command: restore

    projects: '**/Api*.csproj'


#Your build pipeline references an undefined variable named ‘Parameters.projects’. 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.

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

    arguments: '--configuration $(BuildConfiguration)'

  inputs:
    command: publish

    publishWebProjects: false

    arguments: '--configuration $(BuildConfiguration) --output $(build.artifactstagingdirectory)'

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

构建任务运行时有如下日志

我注意到日志指向 2.141.0，因为我正在恢复最新的 SDK 2.1.403 为什么会这样？莫非是托管的VS2017代理不支持.netcore最新版本？

[更新]

我为 Parameters.projects 添加了一个变量

但是构建任务仍然有错误。

Answer 1

张贴以防万一这对将来的任何人有帮助

我将vmImage 设置为ubuntu，设置如下：

projects: '**\*.csproj'

反斜杠把东西扔掉了，我不得不切换到以下内容：

projects: '**/*.csproj'

我从假设 Windows 的指南中复制。够微妙的，我花了一段时间才注意到?

Answer 2

您需要在构建任务中定义您要构建的.csproj 文件。

在您的情况下，定义在变量 $(Parameters.projects) 中。

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

    arguments: '--configuration $(BuildConfiguration)'

您可以在 .csproj 中替换此变量（例如，**/*.csproj 用于所有子文件夹中的所有 .csproj 文件）：

- task: DotNetCoreCLI@2
  displayName: Build
  inputs:
    projects: '**/*.csproj'

    arguments: '--configuration $(BuildConfiguration)'

或者转到变量选项卡并添加Parameters.projects 变量：

Answer 3

我正在尝试在 dotnet 核心中构建和发布多项目解决方案。 解决方案结构为：

sampleTest.API
      sampleTest.API.csproj
sampleTest.Data
      sampleTest.Data.csproj
sampleTest.Identity
      sampleTest.Identity.csproj
sampleTest.Web
      sampleTest.Web.csproj
sampleTest.sln

现在，我只想构建 sampleTest.API dotnet 核心项目。我只需要在构建任务中定义，项目路径如下图。

Azure Devops 中管道构建任务的 yaml 文件如下所示：

steps:
- task: DotNetCoreCLI@2
  displayName: Build
  inputs:
    projects: 'sampleTest.API/*.csproj'
    arguments: '--configuration $(BuildConfiguration)'

如果我们需要基于搜索所有“cs.proj”文件来构建 - 我们会这样做

projects: '**/*.csproj'

在 Azure Devops 中使用经典编辑器的示例构建任务如下所示：
