MSBUILD : error MSB1008: Only one project can be specified

Question

Why am I getting the following Build error?

C:\\WINDOWS\\Microsoft.NET\\Framework\\v3.5\\msbuild.exe C:\\Code\\EduBenesysNET\\EduBenesysNET\\EduBenesysNET.vbproj /t:pu         


        

Answer 1

You need to put qoutes around the path and file name.
So use MSBuild "C:\Path Name\File Name.Exe" /[Options]

Answer 2

This worked for me in TFS MSBuild Argument. Note the number of slashes.

/p:DefaultPackageOutputDir="\\Rdevnet\Visual Studio Projects\Insurance\"

Answer 3

If you are using Any CPU you may need to put it in single quotes.

Certainly when running in a Dockerfile, I had to use single quotes:

# Fails. Gives: MSBUILD : error MSB1008: Only one project can be specified.
RUN msbuild ConsoleAppFw451.sln /p:Configuration=Debug /p:Platform="Any CPU" 

# Passes. Gives: Successfully built 40163c3e0121
RUN msbuild ConsoleAppFw451.sln /p:Configuration=Debug /p:Platform='Any CPU' 

Answer 4

Try to remove the trailing backslash or slash at the end of you publish path and install url

/p:PublishDir="\\BSIIS3\c$\DATA\WEBSITES\benesys.net\benesys.net\TotalEducationTest"
/p:InstallUrl="https://www.benesys.net/benesys.net/TotalEducationTest"

You must have hit a special sequence of characters with the \" and (or) /", but I don't know enough in cmd.exe to figure out.

I personnaly always use Powershell : it's way more friendly and powerful!

Hope it helps!

Answer 5

For future readers.

I got this error because my specified LOG file had a space in it:

BEFORE:

/l:FileLogger,Microsoft.Build.Engine;logfile=c:\Folder With Spaces\My_Log.log

AFTER: (which resolved it)

/l:FileLogger,Microsoft.Build.Engine;logfile="c:\Folder With Spaces\My_Log.log"

I did use solution given in https://www.codingdefined.com/2014/10/solved-msbuild-error-msb1008-only-one.html and that solves the issue. All we need to do is check spaces and ''(check backslashes) in the command
