Q:

I can't see analysis results of SonarQube

I am using sonarqube with jenkins. The execution is successful but I don´t see any report or result. Everything is 0. 
I think the problem is here, but I am not sure.

There is a folder called null, maybe this is the problem but I don't know solve it.
My sonar.properties are:
sonar.projectKey=mykey
sonar.projectName=myproject
sonar.projectVersion=1.0
sonar.sources=.
sonar.language=cs
sonar.sourceEncoding=UTF-8

sonar.analysis.mode        
sonar.verbose=true

UPDATE:
I am trying to downgrade the plugin of C# but I do not find where.

How can I do it?

A:

The same to me in the combinations: sonarqube 5.6.6 - C# 6.0.0.2033
Downgraded C# plugin to 5.4.0.464 and analysis is working. I would like to use latest version :)
