SLF4J error

[SturmB]

I appear to be getting a non-fatal error with this library. Starting up my app with OSThemeDetector.registerListener() in the main() method gives me this:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I'm getting this exact same error too.

Read about the SLF4J logging facade.

This library is using the SLF4J API for logging, but in your project you have to include an actual logging implementation (e.g Log4j2, Logback etc..) to make it work.

I recommend you to use Logback as your underlying logging framework.
Gradle example:

dependencies {
    ...
    implementation 'ch.qos.logback:logback-core:1.2.3'
    implementation 'ch.qos.logback:logback-classic:1.2.3'
}

Here are some articles & video tutorials in this topic:

One question: If I don't want any logger at all, as I don't need logs, would it be better to let this error continue and let the logger be non-operational? For me, the fewer logs and residual data, the better.

Well, if you don't want any logs at all, you can ignore the error.
I don't recommend you to do this because if jSystemThemeDetector fails and logs some error, you won't see it.

I think you should configure Logback and set the default logger level to ERROR, so you won't see any useless debugging/informational logs, just the important ones.
