无法调试msbuild

Question

我正在尝试调试使用msbuild的构建过程。我正在尝试关注this文档。

我这样做是为了添加所需的注册表项

reg add HKLM\SOFTWARE\Microsoft\MSBuild\4.0 /v DebuggerEnabled /d true

然而，当我尝试 msbuild.exe /？

我没有看到调试开关

C:\Program Files (x86)\Microsoft Visual Studio 11.0>msbuild.exe /?
Microsoft (R) Build Engine version 4.0.30319.17929
[Microsoft .NET Framework, version 4.0.30319.18063]

Syntax:              MSBuild.exe [options] [project file]

Description:         Builds the specified targets in the project file. If
                     a project file is not specified, MSBuild searches the
                     current working directory for a file that has a file
                     extension that ends in "proj" and uses that file.

Switches:

  /target:<targets>  Build these targets in this project. Use a semicolon or a
                     comma to separate multiple targets, or specify each
                     target separately. (Short form: /t)
                     Example:
                       /target:Resources;Compile

  /property:<n>=<v>  Set or override these project-level properties. <n> is
                     the property name, and <v> is the property value. Use a
                     semicolon or a comma to separate multiple properties, or
                     specify each property separately. (Short form: /p)
                     Example:
                       /property:WarningLevel=2;OutDir=bin\Debug\

  /maxcpucount[:n]   Specifies the maximum number of concurrent processes to
                     build with. If the switch is not used, the default
                     value used is 1. If the switch is used without a value
                     MSBuild will use up to the number of processors on the
                     computer. (Short form: /m[:n])

  /toolsversion:<version>
                     The version of the MSBuild Toolset (tasks, targets, etc.)
                     to use during build. This version will override the
                     versions specified by individual projects. (Short form:
                     /tv)
                     Example:
                       /toolsversion:3.5

  /verbosity:<level> Display this amount of information in the event log.
                     The available verbosity levels are: q[uiet], m[inimal],
                     n[ormal], d[etailed], and diag[nostic]. (Short form: /v)
                     Example:
                       /verbosity:quiet

  /consoleloggerparameters:<parameters>
                     Parameters to console logger. (Short form: /clp)
                     The available parameters are:
                        PerformanceSummary--Show time spent in tasks, targets
                            and projects.
                        Summary--Show error and warning summary at the end.
                        NoSummary--Don't show error and warning summary at the
                            end.
                        ErrorsOnly--Show only errors.
                        WarningsOnly--Show only warnings.
                        NoItemAndPropertyList--Don't show list of items and
                            properties at the start of each project build.
                        ShowCommandLine--Show TaskCommandLineEvent messages
                        ShowTimestamp--Display the Timestamp as a prefix to any
                            message.
                        ShowEventId--Show eventId for started events, finished
                            events, and messages
                        ForceNoAlign--Does not align the text to the size of
                            the console buffer
                        DisableConsoleColor--Use the default console colors
                            for all logging messages.
                        DisableMPLogging-- Disable the multiprocessor
                            logging style of output when running in
                            non-multiprocessor mode.
                        EnableMPLogging--Enable the multiprocessor logging
                            style even when running in non-multiprocessor
                            mode. This logging style is on by default.
                        Verbosity--overrides the /verbosity setting for this
                            logger.
                     Example:
                        /consoleloggerparameters:PerformanceSummary;NoSummary;
                                                 Verbosity=minimal

  /noconsolelogger   Disable the default console logger and do not log events
                     to the console. (Short form: /noconlog)

  /fileLogger[n]     Logs the build output to a file. By default
                     the file is in the current directory and named
                     "msbuild[n].log". Events from all nodes are combined into
                     a single log. The location of the file and other
                     parameters for the fileLogger can be specified through
                     the addition of the "/fileLoggerParameters[n]" switch.
                     "n" if present can be a digit from 1-9, allowing up to
                     10 file loggers to be attached. (Short form: /fl[n])

  /fileloggerparameters[n]:<parameters>
                     Provides any extra parameters for file loggers.
                     The presence of this switch implies the
                     corresponding /filelogger[n] switch.
                     "n" if present can be a digit from 1-9.
                     /fileloggerparameters is also used by any distributed
                     file logger, see description of /distributedFileLogger.
                     (Short form: /flp[n])
                     The same parameters listed for the console logger are
                     available. Some additional available parameters are:
                        LogFile--path to the log file into which the
                            build log will be written.
                        Append--determines if the build log will be appended
                            to or overwrite the log file. Setting the
                            switch appends the build log to the log file;
                            Not setting the switch overwrites the
                            contents of an existing log file.
                            The default is not to append to the log file.
                        Encoding--specifies the encoding for the file,
                            for example, UTF-8, Unicode, or ASCII
                     Default verbosity is Detailed.
                     Examples:
                       /fileLoggerParameters:LogFile=MyLog.log;Append;
                                           Verbosity=diagnostic;Encoding=UTF-8

                       /flp:Summary;Verbosity=minimal;LogFile=msbuild.sum
                       /flp1:warningsonly;logfile=msbuild.wrn
                       /flp2:errorsonly;logfile=msbuild.err

  /distributedlogger:<central logger>*<forwarding logger>
                     Use this logger to log events from MSBuild, attaching a
                     different logger instance to each node. To specify
                     multiple loggers, specify each logger separately.
                     (Short form /dl)
                     The <logger> syntax is:
                       [<logger class>,]<logger assembly>[;<logger parameters>]
                     The <logger class> syntax is:
                       [<partial or full namespace>.]<logger class name>
                     The <logger assembly> syntax is:
                       {<assembly name>[,<strong name>] | <assembly file>}
                     The <logger parameters> are optional, and are passed
                     to the logger exactly as you typed them. (Short form: /l)
                     Examples:
                       /dl:XMLLogger,MyLogger,Version=1.0.2,Culture=neutral
                       /dl:MyLogger,C:\My.dll*ForwardingLogger,C:\Logger.dll

  /distributedFileLogger
                     Logs the build output to multiple log files, one log file
                     per MSBuild node. The initial location for these files is
                     the current directory. By default the files are called
                     "MSBuild<nodeid>.log". The location of the files and
                     other parameters for the fileLogger can be specified
                     with the addition of the "/fileLoggerParameters" switch.

                     If a log file name is set through the fileLoggerParameters
                     switch the distributed logger will use the fileName as a
                     template and append the node id to this fileName to
                     create a log file for each node.

  /logger:<logger>   Use this logger to log events from MSBuild. To specify
                     multiple loggers, specify each logger separately.
                     The <logger> syntax is:
                       [<logger class>,]<logger assembly>[;<logger parameters>]
                     The <logger class> syntax is:
                       [<partial or full namespace>.]<logger class name>
                     The <logger assembly> syntax is:
                       {<assembly name>[,<strong name>] | <assembly file>}
                     The <logger parameters> are optional, and are passed
                     to the logger exactly as you typed them. (Short form: /l)
                     Examples:
                       /logger:XMLLogger,MyLogger,Version=1.0.2,Culture=neutral
                       /logger:XMLLogger,C:\Loggers\MyLogger.dll;OutputAsHTML

  /validate          Validate the project against the default schema. (Short
                     form: /val)

  /validate:<schema> Validate the project against the specified schema. (Short
                     form: /val)
                     Example:
                       /validate:MyExtendedBuildSchema.xsd

  /ignoreprojectextensions:<extensions>
                     List of extensions to ignore when determining which
                     project file to build. Use a semicolon or a comma
                     to separate multiple extensions.
                     (Short form: /ignore)
                     Example:
                       /ignoreprojectextensions:.sln

  /nodeReuse:<parameters>
                     Enables or Disables the reuse of MSBuild nodes.
                     The parameters are:
                     True --Nodes will remain after the build completes
                            and will be reused by subsequent builds (default)
                     False--Nodes will not remain after the build completes
                     (Short form: /nr)
                     Example:
                       /nr:true

  /preprocess[:file]
                     Creates a single, aggregated project file by
                     inlining all the files that would be imported during a
                     build, with their boundaries marked. This can be
                     useful for figuring out what files are being imported
                     and from where, and what they will contribute to
                     the build. By default the output is written to
                     the console window. If the path to an output file
                     is provided that will be used instead.
                     (Short form: /pp)
                     Example:
                       /pp:out.txt

  /detailedsummary
                     Shows detailed information at the end of the build
                     about the configurations built and how they were
                     scheduled to nodes.
                     (Short form: /ds)

  @<file>            Insert command-line settings from a text file. To specify
                     multiple response files, specify each response file
                     separately.

                     Any response files named "msbuild.rsp" are automatically
                     consumed from the following locations:
                     (1) the directory of msbuild.exe
                     (2) the directory of the first project or solution built

  /noautoresponse    Do not auto-include any MSBuild.rsp files. (Short form:
                     /noautorsp)

  /nologo            Do not display the startup banner and copyright message.

  /version           Display version information only. (Short form: /ver)

  /help              Display this usage message. (Short form: /? or /h)

Examples:

        MSBuild MyApp.sln /t:Rebuild /p:Configuration=Release
        MSBuild MyApp.csproj /t:Clean
                             /p:Configuration=Debug;TargetFrameworkVersion=v3.5


C:\Program Files (x86)\Microsoft Visual Studio 11.0>

我做错了什么？

Answer 1

您使用的是x64操作系统并运行x86进程，因此您应该设置

HKLM\SOFTWARE\Wow6432Node\Microsoft\MSBuild\4.0 

如果你想让它（x86和x64）msbuild

可用

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\4.0]
"DebuggerEnabled"="true"

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSBuild\4.0]
"DebuggerEnabled"="true"

Answer 2

我需要Palo关于Wow6432Node节点的答案，还有一个问题。

当我运行msbuild /?时，我发现我正在运行12.0版本，因此注册表项4.0没有帮助。

当我运行where msbuild时，我发现msbuild已安装在Program Files (x86)中，因此我需要Wow6432Node。

将两者结合起来：

reg add HKLM\SOFTWARE\Wow6432Node\Microsoft\MSBuild\12.0 /v DebuggerEnabled /d true

现在msbuild /?显示调试已启用！

Answer 3

这停止了我的工作，我在网上找不到任何解决方案。

后来我开始在MSBuild反汇编中挖掘其他原因并看到它似乎仍然嵌入了调试代码，但是他们已经改变了标志。

要使其发挥作用（至少在VS 2013上适用于我），请执行以下操作：

1. 在“Visual Studio - ＆gt;调试 - ＆gt;常规”中打开Enable Just My Code

2. 在命令行上将环境变量'MSBUILDDEBUGGING'设置为'1'，即set MSBUILDDEBUGGING=1

3. 在您的项目上运行MSBuild。它应该在几秒钟内要求调试器，一旦你连接，它应该在你的MSBuild的第一行

在深入研究代码之后，我看不到任何其他方式可以为VS 2013附带的MSBuild版本启用调试（除非他们使用反射来解决问题，他们没有理由这样做） 。检查的变量是私有的，只能通过读取该环境变量来设置。

Answer 4

注册表项是否在32位区域？您的命令行正在执行32位版本的msbuild，但是从regedit屏幕截图中可以看出注册表项位于64位部分。在链接文章的一篇评论中特别提到了这一点。
