Screenshot.png shows how I have set up Netbeans. I think you can see everything.
I normally use the *import* org.apache.logging.log4j.Logger and *import* org.apache.logging.log4j.LogManager. The Log4j2 module-info.class file exports *org.apache.logging.log4j*. I have committed a version of the test case with the word logging deleted. And then returned it to what I think is correct in the subsequent commit. I have tried it every way, with and without the classpath entries. BTW adding a jar to both the modulepath and classpath has been a bit hit and miss (ignoring adding log4j-api.jar if it is already on the modulepath) so I used a Library entry for the module path and explicitly added the jars to the classpath. Adding the classpath entries with *import* org.apache.logging.log4j.Logger *import* org.apache.logging.log4j.LogManager means the editor finds the classes Logger and LogManager as you would expect. The Compile File error message is that it cannot find the module log4j.api. https://github.com/cosmiczoo/Log4j2TestCase latest commit is as close as I can get.
