C# 过程'；C:\hostedtoolcache\windows\dotnet\dotnet.exe'；失败，退出代码为1

我的问题是，我有一个在.net core 2.2中创建的项目，问题是我试图用azure管道部署它，但在使用dotnet还原时，它会不断失败并结束构建

它返回的错误如下：

2020-11-21T20:17:30.4639428Z ##[error]**Error: The process 'C:\hostedtoolcache\windows\dotnet\dotnet.exe' failed with exit code 1**

我曾尝试在还原之前安装2.2版以用于该过程，我曾尝试使用nuget.config和global.json

steps:
- task: UseDotNet@2
  displayName: 'Use .NET Core sdk 2.2.x'
  inputs:
    version: 2.2.x
    includePreviewVersions: true
    performMultiLevelLookup: true

- task: DotNetCoreCLI@2
  displayName: 'dotnet restore'
  inputs:
    command: restore
    projects: '**/*.csproj'

- task: NuGetToolInstaller@0
  displayName: 'Use NuGet 4.4.1'
  inputs:
    versionSpec: 4.4.1
    checkLatest: true

- task: NuGetCommand@2
  displayName: 'NuGet restore'
  inputs:
    restoreSolution: '$(Parameters.solution)'

- task: VSBuild@1
  displayName: 'Build solution'
  inputs:
    solution: '$(Parameters.solution)'
    msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactstagingdirectory)\\"'
    platform: '$(BuildPlatform)'
    configuration: '$(BuildConfiguration)'

  displayName: 'Publish symbols path'
  inputs:
    SearchPattern: '**\bin\**\*.pdb'
    PublishSymbols: false
  continueOnError: true

  displayName: 'Publish Artifact'
  inputs:
    PathtoPublish: '$(build.artifactstagingdirectory)'
    ArtifactName: '$(Parameters.ArtifactName)'
  condition: succeededOrFailed()

我使用下面的yaml文件对一个.NETCore2.2项目进行了测试，并获得了成功的结果

trigger:
- master

pool:
  vmImage: 'windows-latest'

steps:
  - task: UseDotNet@2
    inputs:
      version: '2.2.x'
      includePreviewVersions: true
      performMultiLevelLookup: true
  - task: DotNetCoreCLI@2
    inputs:
      command: 'restore'
      projects: '**/*.csproj'

为了缩小问题的范围，我建议您：

创建一个简单的.NETCore2.2项目并推送到DevOps，为这个项目创建一个管道，看看是否可以重现这个问题

将项目克隆到本地，并在本地运行

dotnet restore

命令以查看结果如何

我用你们的管道在最小的解决方案上测试它，它是有效的。你能试着做同样的事情吗？你检查过我的回答了吗？有帮助吗？
