Hello,

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 error below

[13:24:46][MSBuild output] Start MSBuild...
[13:24:46][MSBuild output] 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe' '"@C:\TeamCity\buildAgent\work\999585556854a516\Build\Default.msbuild.teamcity.msbuild.tcargs" C:\TeamCity\buildAgent\work\999585556854a516\Build\Default.msbuild.teamcity'

[13:24:46][MSBuild output] For switch syntax, type "MSBuild /help"


In team city my command line parameters field looks like

Configuration=Debug;DeployPath=E:\websites\umbraco\mysite;Environment=Dev;


As I said when I run a batch file with those parameters it all works.  Any ideas?

Regards

Ismail

I had the exact same error on TeamCity 8.0.5, using the MSBuild ToolsVersion 4.0, MSBuild Version .NET 4.5.

The solution was a change in command line parameters in the MsBuild build step.

I changed it from:

Configuration=Release

To:

/p:Configuration=Release

This seems to have solved the issue.

Shyam Gonella the 2021.2 post-upgrade issue looks like the TW-73745 regression. Here are the workarounds.

Apologies for the inconvenience.
