How to turn off htmlunit logging?

[php-coder]

When I run robot tests (that uses https://github.com/Hi-Fi/robotframework-seleniumlibrary-java and htmlunit), I see the messages from htmlunit and I didn't find a way on how to turn them off.

Example:

$ mvn robotframework:run  -Dincludes=testme

I have the src/test/resources/logback-test.xml file that turns them off but it didn't take into an action. Also, I'm not fully sure whether it's a plugin's responsibility or the robotframework-seleniumlibrary-java.

How I can disable these messages?

@Hi-Fi Perhaps, you have thoughts on that? I'd be grateful for help!

I think this should be handled at the SeleniumLibrary side. Maven plugin doesn't make any actions to other logging than RF level (and mentioned one is coming directly to stdout).

An update in case it can be helpful to someone else:

The loglevel is set and managed by Maven. Here is the details: https://maven.apache.org/maven-logging.html It uses slf4j and SimpleLogger by default. In order to suppress annoying htmlunit messages, I passed the following options:

-Dorg.slf4j.simpleLogger.log.com.gargoylesoftware.htmlunit.DefaultCssErrorHandler=error
-Dorg.slf4j.simpleLogger.log.com.gargoylesoftware.htmlunit.html.InputElementFactory=warn
-Dorg.slf4j.simpleLogger.log.com.gargoylesoftware.htmlunit.IncorrectnessListenerImpl=error

In order to use them always and by default, I put these lines into .m2/jvm.config file within a project.
