Few info which might be helpful to you.

My first guess is that your solution has never been build prior tot he sonar analysis. Build your solution with whatever tool you feel comfortable, msbuild for example then retry mvn sonar:sonar.
If that does not work, ask for help to the user mailing list : http://www.sonarsource.org/support/support/
