When using SonarScanner against a local source, following the suggested manual recipe for classic .NET and MSBuild, I find the following error (look at the bottom line):
SonarScanner for MSBuild 5.5.3
Using the .NET Framework version of the Scanner for MSBuild
Pre-processing started.
Preparing working directories...
11:30:19.134 Updating build integration targets...
11:30:23.344 Failed to request and parse 'http://localhost:9000/api/server/version': An error occurred while sending the request.
What's wrong? How to resolve this?
