Microsoft.Build.CPPTasks.Common找不到Microsoft.Build.Tasks.Core

Question

我剛剛將一個項目從Visual C ++ 2012升級到Visual C ++ 2017，我從MSBuild得到了構建失敗：

C：\\ Program Files（x86）\\ Microsoft Visual Studio \\ 2017 \\ Professional \\ Common7 \\ IDE \\ VC \\ VCTargets \\ Microsoft.Cpp.Current.targets（64,5）：錯誤MSB4062：無法加載“SetEnv”任務從程序集C：\\ Program Files（x86）\\ Microsoft Visual Studio \\ 2017 \\ Professional \\ Common7 \\ IDE \\ VC \\ VCTargets \\ Microsoft.Build.CppTasks.Common.dll。 無法加載文件或程序集'Microsoft.Build.Utilities.Core，Version = 15.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'或其依賴項之一。 該系統找不到指定的文件。 確認聲明是否正確，程序集及其所有依賴項是否可用，以及該任務是否包含實現Microsoft.Build.Framework.ITask的公共類。 [C：\\ SRC \\ MY-project.vcxproj]

Fusion日志顯示不好的事情：

剛剛在Visual Studio社區發布了這個，但在另一個幾乎相同的錯誤報告中，他們將其關閉為“Not a Bug”，原因是我無法理解。 我希望StackOverflow會更有幫助。 :)

Answer 1

Microsoft.Build.CPPTasks.Common找不到Microsoft.Build.Tasks.Core

您似乎正在使用.NET框架中的舊MSBuild.exe。 將項目從VS2012升級到VS2017后，應從以下位置使用MSBuild.exe：

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\MSBuild.exe

那是因為MSBuild現在是Visual Studio的一部分！ ：

從Visual Studio 2013開始，2013版本的MSBuild將作為Visual Studio的一部分而非.NET Framework發布。 這種轉變使我們能夠更快地發展MSBuild。

希望這可以幫助。

Answer 2

您必須編輯此目錄中的文件：

C：\\ Program Files（x86）\\ Microsoft Visual Studio \\ 2017 \\ Community \\ Common7 \\ IDE \\ VC \\ VCTargets

所謂的：

Microsoft.Cpp.Clang.targets

將第17行編輯為：

<UsingTask TaskName="ClangCompile" AssemblyFile="C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\VC\VCTargets\Microsoft.Build.CppTasks.Common.dll"/>

如果這確實產生了您可能需要安裝正確的MSBuild的其他問題，請注意。
