I would guess that you have an error in your config.
# path to source directories (required)
sonar.sources=srcDir1,srcDir2
Are srcDir1 and srcDir2 really the folders where you have your source files? It seems you copied the config from some tutorial and forget to insert the correct folder names.
Also you can remove the following lines, because I don't think you have any custom sonar parameters named like this.
# Additional parameters
sonar.my.property=value
