How do I have spaces in a MSBuild WebProjectOutputDir?

问题

I am trying to call MSBuild from a command line. Everything was working fine when I was using a path that had no spaces, but now I have a path that has spaces and the command is failing.

Command (works):

"C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild.exe" 
/t:Rebuild "C:\Projects\myProject.csproj" 
/p:OutDir=c:\temp\deploy\funAndGames\Deployment\bin\ 
/p:WebProjectOutputDir=c:\temp\deploy\funAndGames\Deployment\ 
/p:Configuration=Release

I then added quotes and changed OutDir to OutPath (doesn't work):

"C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild.exe" 
/t:Rebuild "C:\Projects\myProject.csproj" 
/p:OutPath="c:\temp\deploy\funAndGames\Deployment\bin\" 
/p:WebProjectOutputDir="c:\temp\deploy\funAndGames\Deployment\" 
/p:Configuration=Release

What I am aiming for is something like this (doesn't work):

"C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild.exe" 
/t:Rebuild "C:\Projects\myProject.csproj" 
/p:OutPath="c:\temp\deploy\fun and games\Deployment\bin\" 
/p:WebProjectOutputDir="c:\temp\deploy\fun and games\Deployment\" 
/p:Configuration=Release

Any help on the syntax around OutDir/OutPath and WebProjectOutputDir with spaces? Is it possible? If it isn't does anyone know what the reason is (due to some Url's not having spaces type thing?)

回答1:

Just found this out an answer to this old question. To handle spaces, you should use the escape character \ on all folders. Basically

/p:OutPath="c:\temp\deploy\fun and games\Deployment\bin\"

should be

/p:OutPath="c:\\temp\\deploy\\fun and games\\Deployment\\bin\\"

and magically it works!

回答2:

Try add " ex:

/p:OutPath=""c:\temp\deploy\fun and games\Deployment\bin\""

Msbuild also seems to work with spaces in the OutDir if you switch \ to /, while using quotes:

/p:OutDir="c:/temp/deploy/fun and games/out/"
/p:WebProjectOutputDir="c:/temp/deploy/fun and games/Deployment/"

/p:OutPath="c:\temp\deploy\funAndGames\Deployment\bin\"
----------------------------------------
/p:WebProjectOutputDir="c:\temp\deploy\fun and games\Deployment\"
----------------------------------------

> /p:Configuration=Release

Try this.

Also try via VSStudio GUI. Then copy the settings & try with MS Build.

For me the working solution is:

/p:SQLCMD="\"C:\Program Files\Microsoft SQL Server\100\Tools\Binn\SQLCMD.EXE\""

In other words: Putting all the string into quotes (the external quotes aren't passed as value to MSBuild).

The value inside MSBuild for this property is: "C:\Program Files\Microsoft SQL Server\100\Tools\Binn\SQLCMD.EXE" (with the quotes).

If you have multiple parameters in a switch you can't really 'avoid' the problem by fixing the path. What you can do is put your parameters of the switch between " some_parameters1 some_parameters2 ".

Something like:

<Exec Command="SomeCommand /useMultipleParameterSwitch=&quot;value1:blabla1 | value2:blabla2&quot;"/>

Of course a lot depends of the syntax of the switches but that works for me and my team.

To do this when using a .proj file and your path is included in properties like $(DeployFolder) and $(NuGetExe), you can use """ like this:

<Exec Command="&quot;$(NuGetExe)&quot; pack -OutputDirectory &quot;$(DeployFolder)&quot;" />
