Roslyn Analyzers with Jenkins

Question

We're using SonarLint and StyleCop analyzers within Visual Studio 2015. These work great whilst developing, but was wondering if its possible to run these during a Jenkins build?

Ive seen SonarLint.Runner, so I'm assuming this is possible.

Answer 1

I'm not closely familiar with Jenkins, but you could always install the analyzers into the project as NuGet packages and have them generate warnings and errors as a part of the MsBuild build:

1. Install the following 2 NuGet packages into the project you want to analyze: SonarAnalyzer.CSharp and StyleCop.Analyzers.

2. Optionally configure the severity of individual rules and treat warnings as errors if you want your build to fail in case of warnings.

3. Using MSBuild to compile a project configured like that will result in analyzers warnings and errors surfacing the same way as compiler errors and warnings. You should be able to treat them identically in Jenkins, as well:
