Sonar Qube plugin problems with Flex - actionscript-3

Question

I'm having problems after an upgrade of my Sonar Qube :(
I installed the newest version (5.0) of Sonar Qube using an existing MySQL database. The previous Sonar Qube version was 3.7.4.
I'm using it to analyze a pure ActionScript project using the Flex plugin (Version 2.1).
The problems to me seem threefold:
Just starting the server and viewing previous analysis results I get gray
rects where code quality used to be indicated in shades of green etc.
After installing the Flex plugin using the Update Center this
remains.
Running the sonar-runner (version 2.4) I get two types of errors:
A whole lot of these:
23:35:01.572 DEBUG - Resource org.sonar.api.resources.Directory#46815882[key=path/to/folder] was found using deprecated key. Please update your plugin.
After which the analysis exits with this:
23:35:01.585 INFO - Sensor FlexSquidSensor done: 4508 ms

Now I used to have more plugins installed than just Flex (including the mentioned Cobertura) but after installing those Sonar Qube fails to run at all without too much notification (needless to say the runner won't run either).
Can anyone shed some light on this?
Thanks in advance,
Manno

We already faced this issue with files having old Mac line ends (CR or \r). Git will not consider them as line ends so you end up having less lines in your blame than in your file.
You can "clean" your file using mac2unix utility.
