There is a newer version: 8.6.0.37351

Loggers should:

  private: never be accessible outside of its parent class. If another class needs to log something, it should instantiate its own logger.
  static: not be dependent on an instance of a class (an object). When logging something, contextual information can of course be provided in the messages but the logger should be created at class level to prevent creating a logger along with each object.
  final: be created once and only once per class.


Noncompliant Code Example
With a default regular expression of LOG(?:GER)?:
public Logger logger = LoggerFactory.getLogger(Foo.class);  // Noncompliant


Compliant Solution
private static final Logger LOGGER = LoggerFactory.getLogger(Foo.class);


Exceptions
Variables of type org.apache.maven.plugin.logging.Log are ignored.
