MSBUILD : error MSB1008: Only one project can be specified in teamcity - msbuild

Question

I am trying to run MSBuild with TeamCity.
I have a batch file and I pass into it parameters and the build works. When I try to run through TeamCity I get the error below
[13:24:46][MSBuild output] Start MSBuild...
[13:24:46][MSBuild output] 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe'

In TeamCity my command line parameters field looks like
Configuration=Debug;DeployPath=E:\websites\umbraco\mysite;Environment=Dev;
I did search on StackOverflow and people having similar issues mention ensuring no spaces in commandline parameters also my sln and proj files / pages do not have spaces.
As I said when I run a batch file with those parameters it all works, however, TeamCity fails.

Answer 1

I managed to reproduce the error in the command line: apparently the file contents for Default.msbuild.teamcity.msbuild.tcargs need to be:
/p:Configuration=Debug;DeployPath=E:\websites\umbraco\mysite;Environment=Dev;
instead of:
Configuration=Debug;DeployPath=E:\websites\umbraco\mysite;Environment=Dev;
