Maven solution:

I came across all the same issues as above, and for a maven solution I used 2 dependencies. This configuration is only meant for quick testing if you want a simple project to be using a logger, with a standard configuration. I can imagine you want to make a configuration file later on if you need more information and or finetune your own logging levels.
