NullPointerException on @InjectLogger

I added this to my projects POM:

<dependency>
<groupId>org.apache.onami.logging</groupId>
<artifactId>org.apache.onami.logging.log4j2</artifactId>
<version>3.4.0-incubating</version>
</dependency>


And do @InjectLogger

    @InjectLogger
    Logger logger;

    logger.info("Created"); // NPE here.

What could be the problem?

Good catch, Nino!

I think as well xybrek missed the Module installation, see [1], kind of

+----------------+
Injector injector = Guice.createInjector( new Log4j2LoggingModule(
Matchers.any() ),
    ...
+----------------+

Please let us know, HTH!!!
All the best,
-Simo

My bet would be that you need til install the logger module?
