[英]Nuget Update Packages.config in MSBuild BeforeBuild Step
我一直在尝试编写MsBuild任务,以从Feed网址自动获取Nuget程序包,并自动更新packages.config以更新至最新版本。
// ---- Download and install a package at a desired path ----
var sourceUri = new Uri("FEED URL");
// ---- Update the ‘packages.config’ file ----
var packageReferenceFile = new PackageReferenceFile("../../packages.config");
string packagesPath = "../../packages";
IPackageRepository sourceRepository = PackageRepositoryFactory.Default.CreateRepository(sourceUri.ToString());
PackageManager packageManager = new PackageManager(sourceRepository, packagesPath);
foreach (var sourcePackage in sourceRepository.GetPackages().Where(x => x.IsLatestVersion))
{
if (!packageReferenceFile.EntryExists(sourcePackage.Id + " " + sourcePackage.Version, sourcePackage.Version))
{
var oldPackage = packageReferenceFile.GetPackageReferences().FirstOrDefault(x => x.Id.Contains(sourcePackage.Id));
if (oldPackage != null)
{
packageReferenceFile.DeleteEntry(oldPackage.Id, oldPackage.Version);
}
packageManager.InstallPackage(sourcePackage.Id, SemanticVersion.Parse(sourcePackage.Version.ToFullString()));
// Get the target framework of the current project to add --> targetframework="net452" attribute in the package.config file
var currentTargetFw = Assembly.GetExecutingAssembly()
.GetCustomAttributes(typeof(TargetFrameworkAttribute), false);
var targetFrameworkAttribute = ((TargetFrameworkAttribute[]) currentTargetFw).FirstOrDefault();
// Update the packages.config file
packageReferenceFile.AddEntry(sourcePackage.GetFullName(),
SemanticVersion.Parse(sourcePackage.Version.ToFullString()), false,
new FrameworkName(targetFrameworkAttribute.FrameworkName));
}
}
作为控制台应用程序,它运行良好,并且会自动正确读取文件并更新必要的参考。
当我尝试将其作为MsBuild任务运行时,我一直遇到错误。
这是我放入csproj中的代码(也移至nuget.targets进行测试)

关于如何解决此问题的任何想法似乎都找不到解决方案。 总体而言,在CI构建过程中执行此操作的第一步是使nuget保持最新状态。
谢谢蒂姆
刚打电话
nuget restore "your_solution.sln"
不要通过用C#代码编写轮子来重新发明轮子。
MSBuild BeforeBuild步骤中的Nuget Update Packages.config
不知道您的代码问题来自哪里。 使用NuGet.exe
还原和更新解决方案,而不是尝试使用C#代码,可能会更简单。
因此,您可以在MSBuild BeforeBuild步骤中添加以下nuget命令行
<Target Name="BeforeBeforeBuild" BeforeTargets="BeforeBuild">
<Exec Command="$(YourNuGetPath)\nuget.exe restore "$(YouSolutionPath)\YourSolution.sln" -PackagesDirectory "$(YouPackagePath)\packages"" />
<Exec Command="$(YourNuGetPath)\nuget.exe update "$(YouSolutionPath)\YourSolution.sln"" />
</Target>
注意:如果使用的是Visual Studio,Visual Studio将在构建过程中自动检查丢失的软件包并还原它们: Package Restore 。
希望这可以帮助。
