[英]Nuget Update Packages.config in MSBuild BeforeBuild Step
我一直在嘗試編寫MsBuild任務,以從Feed網址自動獲取Nuget程序包,並自動更新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));
}
}
作為控制台應用程序,它運行良好,並且會自動正確讀取文件並更新必要的參考。
當我嘗試將其作為MsBuild任務運行時,我一直遇到錯誤。
這是我放入csproj中的代碼(也移至nuget.targets進行測試)

關於如何解決此問題的任何想法似乎都找不到解決方案。 總體而言,在CI構建過程中執行此操作的第一步是使nuget保持最新狀態。
謝謝蒂姆
剛打電話
nuget restore "your_solution.sln"
不要通過用C#代碼編寫輪子來重新發明輪子。
MSBuild BeforeBuild步驟中的Nuget Update Packages.config
不知道您的代碼問題來自哪里。 使用NuGet.exe
還原和更新解決方案,而不是嘗試使用C#代碼,可能會更簡單。
因此,您可以在MSBuild BeforeBuild步驟中添加以下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將在構建過程中自動檢查丟失的軟件包並還原它們: Package Restore 。
希望這可以幫助。
