Thanks for the logs. They contain messages like:
CSC : warning CS8032: An instance of analyzer SonarAnalyzer.Rules.CSharp.MutableFieldsShouldNotBePublicReadonly cannot be created from E:\TEMP\TEMPFILES\.sonarqube\resources\3\SonarAnalyzer.CSharp.dll : Could not load file or assembly 'Microsoft.CodeAnalysis, Version=1.3.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified..
which means that the C# compiler (e.g. Roslyn) version is not supported. You need to use MSBuild.exe that comes with Visual Studio 2015 Update 3 (or Visual Studio 2017 any update).
The MSBuild.exe version is printed when you execute it.
