MSBUILD : error MSB1008: Only one project can be specified

Why am I getting the following Build error?

C:\WINDOWS\Microsoft.NET\Framework\v3.5\msbuild.exe C:\Code\EduBenesysNET\EduBenesysNET\EduBenesysNET.vbproj /t:publish /p:Configuration=Release /p:Platform=AnyCPU /v:detailed /p:PublishDir="\\BSIIS3\c$\DATA\WEBSITES\benesys.net\benesys.net\TotalEducationTest\"  /p:InstallUrl="https://www.benesys.net/benesys.net/TotalEducationTest/"  /p:ApplicationVersion=1.0.1.198  /p:ProductName="Total Education TEST"   /p:PublisherName="BeneSys, Inc."  /p:UpdateRequired="True"  /p:MinimumRequiredVersion=1.0.1.198

MSBUILD : error MSB1008: Only one project can be specified.
Switch: Education

For switch syntax, type "MSBuild /help"

I do not see how a second project is being specified.
Is it stored in a project file somewhere?

Solution 1:

It turns out the trailing slash in the PublishDir property is escaping the end quote. Escaping the trailing slash solved my problem.

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

This way we can use quotes for paths that have whitespace in properties that MSBuild requires the trailing slash.

I know this is an old post, but I feel like I needed to share this with someone :-)

Solution 2:

SOLUTION
Remove the Quotes around the /p:PublishDir setting

i.e.
Instead of quotes

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

Use no quotes

/p:PublishDir=\\BSIIS3\c$\DATA\WEBSITES\benesys.net\benesys.net\TotalEducationTest\  

I am sorry I did not post my finding sooner. I actually had to research again to see what needed to be changed. Who would have thought removing quotes would have worked? I discovered this when viewing a coworkers build for another solution and noticed it did not have quotes.
