最后一个版本的非预览asp .net核心3在蔚蓝管道

Question

在azure管道中安装.net核心3.0不可预览的命令是什么？

我试过

- task: DotNetCoreInstaller@0
  displayName: 'Install .net core 3.0'
  inputs:
    packageType: 'sdk'
    version: '3.0.100'

而构建失败了

Getting URL to download .NET Core sdk version: 3.0.100.

Could not fetch download information for version 3.0.100. Please check if the version specified is correct. You can refer the link for supported versions => https://github.com/microsoft/azure-pipelines-tasks/blob/master/Tasks/DotNetCoreInstallerV0/externals/releases.json. Falling back to creating convention based URL.

##[warning]Kindly upgrade to new major version of this task 'Use .NET Core (2.*)' for installing newer versions of .NET Core. '0.*' task version might not be able to download newer .NET core versions. To know more about 'Use Dot Net (2.*)', refer https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/tool/dotnet-core-tool-installer?view=azure-devops. 3.0.100

在起作用之前：

- task: DotNetCoreInstaller@0
  displayName: 'Install .net core 3.0 (preview)'
  inputs:
    packageType: 'sdk'
    version: '3.0.100-rc1-014190'

Answer 1

我测试了你的下载任务，它对我很好。

但是，您可以尝试使用新的安装程序任务UseDotNet@2。

- task: UseDotNet@2
  displayName: Install .NET Core 3.0 SDK
  inputs:
    packageType: 'sdk'
    version: '3.0.100'

更新：

为了使用.net3.0，您可能需要使用DotnetCoreClI任务来恢复、构建和测试项目的，下面是一个示例：

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

steps:
- task: UseDotNet@2
  displayName: Install .NET Core 3.0 SDK
  inputs:
    packageType: 'sdk'
    version: '3.0.100'

- task: DotNetCoreCLI@2
  inputs:
    command: 'restore'
    projects: '$(solution)'
    feedsToUse: 'select'
  displayName: Restore

- task: DotNetCoreCLI@2
  inputs:
    command: 'build'
    projects: '$(project)'
  displayName: Build

- task: DotNetCoreCLI@2
  inputs:
    command: 'test'
    projects: '$(project)'
  displayName: Test

Answer 2

感谢您的回复。

这对我来说很有用，但是有命令

• 任务: UseDotNet@2

构建稍后在以下位置失败：

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

Answer 3

我对同样的问题感到震惊，但错误不同。

​

​

我就是这样执行powershell脚本的

$globaljson = '{"sdk": {"version": "3.0.100-preview3-010431"}}';
$globaljson | out-file $(Agent.ToolsDirectory)/dotnet2

这就是安装程序被调用的方式。

我不知道我在这里错过了什么。
