I gave it a shot, but didn’t see anything or even the line ‘Parsing {…xml}’ which is supposed to be indicative of it picking up a cobertura report to parse.
Basically at this point I’m going to fork the sonar plugin, add some more debug information to try to figure out why the report isn’t being parsed, and then I’ll install my own custom verison of the plugin once I figure out why. I’ll reply back here when I have more information later today.
