錯誤MSB4018：構建服務器上的「SignFile」任務意外失敗

Question

我有一個clickonce解決方案，適用於安裝了VS 2015的多個開發人員計算機。但是，它不適用於我們的buildserver，它帶有這個signFile錯誤。我已經安裝了

• 生成工具2015年更新3
• 淨4.6.2 SDK
• Windows軟件開發工具包

但apparantly的路徑signtool.exe沒有正確設置。如果我禁用清單的簽名，它將繼續，但會出現setup.bin丟失的錯誤。

有沒有人有一個很好的線索如何解決SignFile問題？

Answer 1

被拋出對Microsoft.Build.Tasks.Deployment.ManifestUtilities.SecurityUtilitiesline 195的錯誤，這是在下面的方法：

internal static string GetPathToTool() 
    { 
     string pathToDotNetFrameworkSdkFile = ToolLocationHelper.GetPathToDotNetFrameworkSdkFile(ToolName(), TargetDotNetFrameworkVersion.Version35); 
     if (pathToDotNetFrameworkSdkFile == null) 
     { 
      pathToDotNetFrameworkSdkFile = Path.Combine(Environment.CurrentDirectory, ToolName()); 
     } 
     if (!File.Exists(pathToDotNetFrameworkSdkFile)) 
     { 
      pathToDotNetFrameworkSdkFile = null; 
     } 
     return pathToDotNetFrameworkSdkFile; 
    } 

的直接原因是，Environment.CurrentDirectory返回null，但更突出的一個是ToolLocationHelper.GetPathToDotNetFrameworkSdkFile(ToolName(), TargetDotNetFrameworkVersion.Version35)也恢復null。

上面的代碼的類的特定版本的唯一快照，但硬編碼枚舉值TargetDotNetFrameworkVersion.Version35告訴我，問題是，生成工具2015年更新3取決於比版本的.NET SDK其他的4.6.2。

UPDATE：

爲了幫助識別特定的SDK版本，我在https://github.com/Microsoft/msbuild/releases從更新3版本拉低了源代碼。

internal static string GetPathToTool(System.Resources.ResourceManager resources) 
    { 
#pragma warning disable 618 // Disabling warning on using internal ToolLocationHelper API. At some point we should migrate this. 
     string toolPath = ToolLocationHelper.GetPathToWindowsSdkFile(ToolName, TargetDotNetFrameworkVersion.VersionLatest, VisualStudioVersion.VersionLatest); 
     if (toolPath == null) 
      toolPath = ToolLocationHelper.GetPathToWindowsSdkFile(ToolName, TargetDotNetFrameworkVersion.Version45, VisualStudioVersion.Version110); 
     if (toolPath == null) 
      toolPath = Path.Combine(ToolLocationHelper.GetPathToDotNetFrameworkSdk(TargetDotNetFrameworkVersion.Version40, VisualStudioVersion.Version100), "bin", ToolName); 
     if (toolPath == null) 
      toolPath = Path.Combine(Directory.GetCurrentDirectory(), ToolName); 
     if (!File.Exists(toolPath)) 
      throw new ApplicationException(String.Format(CultureInfo.CurrentCulture, resources.GetString("SecurityUtil.SigntoolNotFound"), toolPath)); 
     return toolPath; 
#pragma warning restore 618 
    } 

進一步翻閱的解決方案，我決定構建工具的最新版本（安裝了一個），不包括change到Shared\FrameworkLocationHelper.cs是增加了對框架4.6.2支持。因此，要回答您的後續問題，安裝4.6.1 SDK的應該執行技巧。

更新2：

的OP識別的替代解決方案：顯式設置TargetFrameworkSDKToolsDirectory屬性的值，例如在從命令行調用msbuild.exe時，通過添加/p:TargetFrameworkSDKToolsDirectory=PATH TO SIGNTOOL.EXE(?)作爲參數。
