​Hey,

I am getting this error when running analysis in publish mode with the msbuild sonar scanner on a c# project. Any idea what causes it?

Full command line output in attached (cmd.txt)

SonarQubeAnalysisConfig from .sonarqube\conf directory is attached (SonarQubeAnalysisConfig.xml) 

Unhandled Exception: System.FormatException: Input string was not in a correct format.

Hi.

What version of Visual Studio are you using (looks from the log like VS2015, but which update)?

The analyzers run during the build produce a json file containing the issues. Unfortunately, the version of Roslyn used by the RTM version of VS2015 had a bug in it that meant it produced invalid json. The scanner tries to work round this issue by detecting and fixing up invalid json files. It looks from the log like the code is failing at this point i.e. for some reason the json issues file is not valid json. The scanner should handle this gracefully, but unfortunately it isn't (it's only expected JSON exceptions, but here you are getting a FormatException).

If you are using the RTM version of Visual Studio then try applying one of the VS updates (preferably at least VS2015 update 3 - if I remember correctly that is the earliest update that MS still support)

Regards,

Duncan

Hey,

I am actually stuck with visual studio 2013 (ultimate edition).

Any chance to get this running with this version of VS? 

Many thanks!
