Sonar scanner analysis hangs out on util.lang.ConcreteReceiverGuard

Question

I am running a sonar analysis of a java project with sonar-java and the following configuration:

SonarQuber Servcer 5.6
Sonar-java 4.10.0.10260
SonarQube Scanner 3.0.3.778
Java 1.8.0_121 Oracle Corporation (64-bit)

When I start a sonar analysis it seems to be working until I got the following logs and then the analysis simply continues to run forever (last time it ran all night long):

util.lang.ConcreteReceiverGuard reports a runtime deprecation: calling method "padl.kernel.impl.CodeLevelModel.create()" from class "it.unibz.sonarqube_plugin.ExampleSensor"
Please use the methods in "padl.generator.helper.ModelGenerator" to obtain code-level models.

How can I see what is going wrong and how to fix it?

I should note that:

• Several projects use the same server and the same rules, they have the same message but the analysis continues.
• Even if I run sonar-scanner -X with the debug flag I don't get more messages.

If needed the full log of the analysis is here (note that the issue also appear when the analysis is started by a jenkins post job task):

Answer 1

Your analysis fails during execution of Sensor ExampleSensor. This analysis step is provided by one of the plugins installed on the SonarQube server (apparently it.unibz.sonarqube_plugin.ExampleSensor).

You need to contact the maintainers of this (potentially proprietary) plugin and submit this to them (can be a bug). Or at the very least share this context with your SonarQube admin (in case there is no intent to have an ExampleSensor affect real-life projects).
