使用 Cake 为 .Net Standard 2.0 lib 构建 NuGet 包

Question

我创建了一个基于 .Net Standard 2.0 的类库，并使用 Cake 构建了项目/解决方案，但我找不到如何为该库构建 NuGet 包。 NuGetPack 不起作用。

Answer 1

你真的有两个选择。 NuGetPack 将继续工作，我在我维护的几个 Cake Addins 上使用这种方法。您能否详细说明您所看到的问题？

另一个选项是使用DotNetCorePack 别名。您可以在此文件中看到这一点（它是 Cake.Recipe 脚本集的一部分）：

https://github.com/cake-contrib/Cake.Recipe/blob/develop/Cake.Recipe/Content/nuget.cake

它也记录在这里：

https://cakebuild.net/api/Cake.Common.Tools.DotNetCore/DotNetCoreAliases/0F7A518E

var projects = GetFiles(BuildParameters.SourceDirectoryPath + "/**/*.csproj")
    - GetFiles(BuildParameters.SourceDirectoryPath + "/**/*.Tests.csproj");

var settings = new DotNetCorePackSettings {
    NoBuild = true,
    Configuration = BuildParameters.Configuration,
    OutputDirectory = BuildParameters.Paths.Directories.NuGetPackages,
    ArgumentCustomization = (args) => {
        if (BuildParameters.ShouldBuildNugetSourcePackage)
        {
            args.Append("--include-source");
        }
        return args
            .Append("/p:Version={0}", BuildParameters.Version.SemVersion)
            .Append("/p:AssemblyVersion={0}", BuildParameters.Version.Version)
            .Append("/p:FileVersion={0}", BuildParameters.Version.Version)
            .Append("/p:AssemblyInformationalVersion={0}", BuildParameters.Version.InformationalVersion);
    }
};

foreach (var project in projects)
{
    DotNetCorePack(project.ToString(), settings);
}

NuGetPack 需要 nuget.exe 4.4.x 或更高版本才能使 .NET Standard 正常工作，也就是说，还有使用 nuget.exe 的替代方法。

如果您使用的是 .NET Core Cli，则使用 DotNetCorePack 别名。

如果您使用 MSBuild 进行构建，则新 SDK csproj 的 MSBuild now 有一个 Pack 目标，可能如下所示：

var configuration           = Argument("configuration", "Release");
FilePath solution           = MakeAbsolute(File("./src/MySolution.sln"));
DirectoryPath artifacts     = MakeAbsolute(Directory("./artifacts"));
var version = //some version login i.e. GitVersion
var semVersion = //some version login i.e. GitVersion

Func<MSBuildSettings,MSBuildSettings>
    commonSettings         = settings => settings
                                .UseToolVersion(MSBuildToolVersion.VS2017)
                                .SetConfiguration(configuration)
                                .SetVerbosity(Verbosity.Minimal)
                                .WithProperty("PackageOutputPath", artifacts.FullPath)
                                .WithProperty("VisualStudioVersion", "15.0")
                                .WithProperty("Version", semVersion)
                                .WithProperty("AssemblyVersion", version)
                                .WithProperty("FileVersion", version);

Task("Clean")
  .Does(() =>
  {
    //some clean logic
  });

Task("Restore-NuGet-Packages")
    .IsDependentOn("Clean")
    .Does(() =>
{
    NuGetRestore(solution,
        new NuGetRestoreSettings {
            Verbosity = NuGetVerbosity.Quiet
            });
});

Task("Build")
    .IsDependentOn("Restore-NuGet-Packages")
    .Does(() =>
{
    MSBuild(solution, settings => commonSettings(settings).WithTarget("Build"));
});



Task("Create-NuGet-Package")
    .IsDependentOn("Build")
    .Does(() =>
{
     MSBuild(project,
        settings => commonSettings(settings)
                        .WithTarget("Pack")
                        .WithProperty("IncludeSymbols","true"));
});

Answer 3

我无法让NuGetPack 工作，尽管那可能是 NuGet exe 版本（尽管我相当确定它是 4.4.something）。

我最终在我的蛋糕脚本中使用了以下代码来打包核心项目：

private void PackCoreProject(string nugetVersion, string outputDirectory, string projectFile)
{
    var settings = GetCorePackSettings(nugetVersion, outputDirectory);
    DotNetCorePack(projectFile, settings);
}

private DotNetCorePackSettings GetCorePackSettings(string nugetVersion, string outputDirectory)
{
    // Version fun with dotnet core... https://stackoverflow.com/questions/42797993/package-version-is-always-1-0-0-with-dotnet-pack

    Func<Cake.Core.IO.ProcessArgumentBuilder, Cake.Core.IO.ProcessArgumentBuilder> appendVersionToArgs = 
        new Func<Cake.Core.IO.ProcessArgumentBuilder, Cake.Core.IO.ProcessArgumentBuilder>(_ => 
    {
        return _.Append($"/p:Version={nugetVersion}");
    });

    return new DotNetCorePackSettings
    {
        VersionSuffix = GetNuGetVersionSuffix(),
        OutputDirectory = outputDirectory,
        Configuration = configuration,
        NoBuild = true,
        IncludeSymbols = true,
        IncludeSource = true,
        ArgumentCustomization = appendVersionToArgs,
    };
}

private string GetNuGetVersion()
{
    // If the branch is master or hotfix, build a normal version as these are due for release.
    if (IsReleaseBranch())
    {
        return $"{major}.{minor}.{build}";
    }

    return $"{major}.{minor}.0-{GetNuGetVersionSuffix()}";
}

请注意，我必须通过构建器功能手动将版本添加到末尾。

IsReleaseBranch 方法只是一个开关，将 master 或 hotfix 标记为有效的发布分支，并将其他任何内容标记为 dev，因此当确定 NuGet 包版本时，dev build 是预发布的。
