Github操作：推送nuget xamarin.forms包

如何解决Github操作：推送nuget xamarin.forms包

我正在尝试配置一个GitHub操作，该操作构建我的多目标Xamarin.Forms插件并将该包推送到GitHub和NuGet。将包推送到GitHub和NuGet shouldn't be much of a problem anymore。我在GitHub CI上构建多目标nuget包时遇到了麻烦。

首先，我执行了以下GitHub动作：

name: .NET Core

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - name: Checkout
      uses: actions/checkout@v2
    - name: Setup .NET Core
      uses: actions/setup-dotnet@v1.5.0
      with:
        dotnet-version: 3.1.301
        # Authenticates packages to push to GPR
        source-url: https://nuget.pkg.github.com/${{ github.repository_owner }}/index.json
      env:
        NUGET_AUTH_TOKEN: '%NUGET_AUTH_TOKEN%'
    - name: Install dependencies
      run: dotnet restore
    - name: Build
      run: dotnet build --configuration Release --no-restore
    - name: Test
      run: dotnet test --no-restore --verbosity normal
    - name: Pack
      run: dotnet pack --no-build --configuration Release MintPlayer.MVVM/MintPlayer.MVVM.csproj --output .
    - name: PushNuget
      run: dotnet nuget push *.nupkg --source https://api.nuget.org/v3/index.json --api-key ${{ secrets.PUBLISH_TO_NUGET_ORG }} --skip-duplicate
    - name: PushGithub
      #run: dotnet nuget push *.nupkg --source https://nuget.pkg.github.com/${{ github.repository_owner }}/index.json --api-key ${{ github.token }} --no-symbols --skip-duplicate
      run: dotnet nuget push *.nupkg --no-symbols --skip-duplicate
      env:
        NUGET_AUTH_TOKEN: ${{ github.token }}

以及我的解决方案根目录中的以下nuget.config，以使该操作知道nuget源，以下载所需的NuGet软件包：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
  </packageSources>
</configuration>

将此配置推送到我的GitHub存储库时，在 Build 阶段出现以下错误：

/Users/runner/work/MintPlayer.MVVM/MintPlayer.MVVM/Demo/MintPlayer.MVVM.Demo/MintPlayer.MVVM.Demo.UWP/MintPlayer.MVVM.Demo.UWP.csproj(175,3): error MSB4019: The imported project "/Users/runner/hostedtoolcache/dncs/3.1.301/x64/sdk/3.1.301/Microsoft/WindowsXaml/v16.0/Microsoft.Windows.UI.Xaml.CSharp.targets" was not found.

然后，我修改了工作流程以改用msbuild（至少直到构建阶段：

name: .NET Core

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build:

    runs-on: macos-latest

    steps:
    - name: Checkout
      uses: actions/checkout@v2
    - name: Setup .NET Core
      uses: actions/setup-dotnet@v1.5.0
      with:
        dotnet-version: 3.1.301
        # Authenticates packages to push to GPR
        source-url: https://nuget.pkg.github.com/${{ github.repository_owner }}/index.json
      env:
        NUGET_AUTH_TOKEN: '%NUGET_AUTH_TOKEN%'
    - name: Install dependencies
      #run: dotnet restore
      #env:
      #  NUGET_AUTH_TOKEN: ${{ github.token }}
      run: msbuild /t:restore
    - name: Build
      #run: dotnet build --configuration Release --no-restore
      run: msbuild Library/MintPlayer.MVVM/MintPlayer.MVVM.csproj /p:Configuration=Release /p:RestorePackages=false
    - name: Test
      run: dotnet test --no-restore --verbosity normal
    - name: Pack
      run: dotnet pack --no-build --configuration Release MintPlayer.MVVM/MintPlayer.MVVM.csproj --output .
    - name: PushNuget
      run: dotnet nuget push *.nupkg --source https://api.nuget.org/v3/index.json --api-key ${{ secrets.PUBLISH_TO_NUGET_ORG }} --skip-duplicate
    - name: PushGithub
      #run: dotnet nuget push *.nupkg --source https://nuget.pkg.github.com/${{ github.repository_owner }}/index.json --api-key ${{ github.token }} --no-symbols --skip-duplicate
      run: dotnet nuget push *.nupkg --no-symbols --skip-duplicate
      env:
        NUGET_AUTH_TOKEN: ${{ github.token }}

但是它仍然无法正常工作。

Github操作中的控制台在成吨的文本之间显示以下错误：

/Users/runner/.nuget/packages/msbuild.sdk.extras/2.1.2/Build/LanguageTargets/CheckMissing.targets(44,5): error : The specified language targets for uap10.0.16299 is missing. Ensure correct tooling is installed for 'uap'. Missing: '/Library/Frameworks/Mono.framework/Versions/6.12.0/lib/mono/xbuild/Microsoft/WindowsXaml/v16.0/Microsoft.Windows.UI.Xaml.CSharp.targets' [/Users/runner/work/MintPlayer.MVVM/MintPlayer.MVVM/Library/MintPlayer.MVVM/MintPlayer.MVVM.csproj]

所以这可能意味着UWP工具在macOS上不可用。从输出中可以看到android构建成功，iOS构建成功，但是UWP构建失败，并显示前一条消息。

如何在GitHub CI中构建Xamarin.Forms包并将其推送到我的nuget源？

编辑：

好的，我将工作流程修改为使用Windows and MSBuild而不是macos and dotnet，这使我更加接近了。

name: .NET Core

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build:

    runs-on: windows-latest

    steps:
    - name: Checkout
      uses: actions/checkout@v2
    
    - name: Setup .NET Core
      uses: actions/setup-dotnet@v1.5.0
      with:
        dotnet-version: 3.1.301
        # Authenticates packages to push to GPR
        source-url: https://nuget.pkg.github.com/${{ github.repository_owner }}/index.json
      env:
        NUGET_AUTH_TOKEN: '%NUGET_AUTH_TOKEN%'
    
    # Add  MsBuild to the PATH: https://github.com/microsoft/setup-msbuild
    - name: Setup MSBuild.exe
      uses: microsoft/setup-msbuild@v1.0.1
    
    - name: Install dependencies
      run: msbuild /t:restore
      env:
        NUGET_AUTH_TOKEN: ${{ github.token }}
    
    - name: Build
      run: msbuild Library/MintPlayer.MVVM/MintPlayer.MVVM.csproj /p:Configuration=Release /p:RestorePackages=false /p:OutputPath=../..
    
    - name: PushNuget
      run: dotnet nuget push *.nupkg --source https://api.nuget.org/v3/index.json --api-key ${{ secrets.PUBLISH_TO_NUGET_ORG }} --skip-duplicate
    - name: PushGithub
      run: dotnet nuget push *.nupkg --no-symbols --skip-duplicate
      env:
        NUGET_AUTH_TOKEN: ${{ github.token }}

此操作成功将我的nuget软件包同时推送到Nuget和Github，但是当我在Xamarin.Forms项目中安装此软件包时，我只在所有项目中获得UWP类，而这些仅应可用在UWP定位项目中。

与我右键单击多目标项目并单击 Pack 命令不同，该软件包实际上可以正常工作。有谁知道我该如何解决？

解决方法

这是我的最终工作流程：

    branches: [ master ]
  pull_request:
    branches: [ master ]

        source-url: https://nuget.pkg.github.com/${{ github.repository_owner }}/index.json
      env:
