How to set log levels in jbang

[ennishol]

I've implemented a simple kafka producer script, which worked great except log level by default is DEBUG and it pollutes the output. How do you generally set the log level, programmatically or with a .properties file? Is there any example?

I've tried to set //FILES log4j.properties with no effect

It would be great if there was a shortcut from jbang. something like //LOGLEVEL WARN or similar to avoid an additional file?

Turns out it was logback

        Logger root = (Logger) LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
        root.setLevel(ch.qos.logback.classic.Level.WARN);

solved it for me.
