Build fails when try to run SonarQube Scanner for MSBuild on C# project

Question

I am trying to analyze my C# code with SonarQube Scanner for MSBuild from command line.

I have installed the SonarQube Scanner for MSBuild 2.2.0.24 (http://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner+for+MSBuild) and have all the prerequisites.

I am running the following commands:

SonarQube.Scanner.MSBuild.exe begin /k:"MyProject" /n:"My Project" /v:"1.0.0.0"

"C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe" /t:Rebuild

SonarQube.Scanner.MSBuild.exe end

But when I run msbuild on my solution (.Net Framework 4.5.1) the build fails. The solution builds successfully when I am not doing Sonar scan so it must have something to do with the sonar scanner plugin.

In SonarQube.Analysis.xml I have only provided sonar.host.url, sonar.login and sonar.password.

This is the output from the msbuild:

Build FAILED.

This issue has been resolved by editing the csproj file for the main project in our solution. It initially looked like this:

<OutputPath>$(BuildOutputPath)\bin\$(MSBuildProjectName)\$(Configuration)</OutputPath>

But the $(MSBuildProjectName) variable did seem to work when running msbuild during Sonar scan, it generated the
xxc3zd2a.tmp_proj folder, instead of the actual project name. When replacing
$(MSBuildProjectName) with the project name it worked. Our solution has 4 project but I only changed one of them.

Note that when only running msbuild no changes to csproj file is needed...
