Sonar for Eclipse: unable to run local analysis - eclipse-plugin

Question

I have successfully installed sonar plug-in for eclipse, however when I try to 'Run Local Analysis' for sonar, eclipse gives an error saying:
An internal error occurred during: "Sonar Analysis".
Unable to create markers
and console for Sonar has following info printed:
Usage: javaw [-options] class [args...]

or javaw [-jar] [-options] jarfile [args...]

where options include:
-cp -classpath

-D=

-verbose[:class|gc|jni]
enable verbose output
-version print product version
-version:
