Bug when developing a python parser plugin

I am trying to develop a Java plugin to parse Python scripts, but I am not able to get it to evaluate the measurements correctly. When I start SonarQube, in the file sonarqube-9.4.0.54424\logs/web it appears:


What does it mean and how can I solve it? Could this be causing my plugin not to evaluate the measurements?
If someone knows if the bug is in the pom.xml file… my pom.xml file is:

Hi!

Sorry, I don’t understand what you’re trying to achieve.
What are the “measurements” you mention?
What makes you think that it doesn’t work?
The line you highlighted in the logs seems to indicate that your plugin is loaded by the SonarQube server.
