Why SonarQube Scanner for MSBuild does not work with MSBuild 15.0?

Question

I rencently upgraded my Visual Studio from 2015 to 2017. The build process now uses MSBuild 15.0 so I can use C#7.

I installed a SonarQube server from the latest version 6.3 and I use the latest version of the C# scanner 2.2.0.24.

I'm trying to make an analysis of my code, from the folder where my solution is:

1. Run SonarQube.Scanner.MSBuild.exe begin /key:"myproject".

   Default properties file was found at C:\myfolder\SonarQube.Analysis.xml
   Loading analysis properties from C:\myfolder\SonarQube.Analysis.xml

2. Run MSBuild version 15.1.548.43366.

   ...
   
   Build succeeded.
       0 Warning(s)
       0 Error(s)
   

3. Run SonarQube.Scanner.MSBuild.exe end.

   The SonarQube MSBuild integration failed: SonarQube was unable to collect the required information about your projects.
   Possible causes:
   1. The project has not been built - the project must be built in between the begin and end steps
   2. An unsupported version of MSBuild has been used to build the project. Currently MSBuild 12.0 upwards are supported
   3. The begin, build or end steps have not all been launched from the same folder
   Generation of the sonar-properties file failed. Unable to complete SonarQube analysis.

I can't figure out why it is failing.

Does the c# sonarqube scanner 2.2 support MSBuild 15.0?

Answer 1

MSBuild 15 is not supported by the SonarQube Scanner for MSBuild 2.2.

The good news is that we are about to release version 2.3 of the Scanner for MSBuild that fixes this bug. You can read more on the bug ticket SONARMSBRU-288.

The release will happen within the first half of April 2017.
