Sonar C# project with multiple modules using the Simple Java Runner

Question

I'm trying Sonar 3.2 with C# projects (the only plugins are C# Core and C# FX Cop) and using the Simple Java Runner.

It worked fine on a solution with a single project, but when I tried to analyse using a solution with 2 projects I always get the following error:

    ... 3 more

The solution folder contains the following sonar-project.properties:

# Project identification
sonar.projectKey=com.project.btg
sonar.projectVersion=1.0
sonar.projectName=BTG

# Info required for Sonar
sonar.sources=.
sonar.language=cs

sonar.dotnet.visualstudio.solution.file=Sonar.project.sln
sonar.dotnet.buildPlatform=x86
sonar.dotnet.buildConfiguration=Debug

sonar.modules=Project1,Project2

#modules specific configuration
Project1:sonar.sources=.\Project1
Project1:sonar.projectName=Project 1

Project2:sonar.sources=.\Project2
Project2:sonar.sources=Project 2

The solution only has this 2 projects.

I tried adding the modules configuration in a sonar-project.properties for each project with just:

# Project identification
sonar.projectName=Project 1

For the single project I used I had:

# Project identification
sonar.projectKey=com.Project1
sonar.projectVersion=1.0
sonar.projectName=Project 1

# Info required for Sonar
sonar.sources=.
sonar.language=cs

I feel I'm missing something very simple, but I couldn't find much information on this.

If someone can help me with this I have an additional question: Can you analyse a hybrid solution of C++ and C# project?

Thanks

The support of multi-module is built-in for the C# plugins, you don't need to (and should not) specify:

sonar.modules=Project1,Project2

#modules specific configuration
Project1:sonar.sources=.\Project1
Project1:sonar.projectName=Project 1

Project2:sonar.sources=.\Project2
Project2:sonar.sources=Project 2

, nor add a "sonar-project.properties" inside each module.

The C# Plugins rely on the SLN file to automatically discover the modules. Take a look at our sample application, and just replace the Maven POM by a single "sonar-project.properties" file.
