How to enable Grails 2 logging for development

Question

What's the simplest way to show Grails app log for a developer who is new to Grails?

It could help learning Grails magics.

Answer 1

Groovy 2.x : open grails-app/conf/Config.groovy , and replace contents of log4j block with:

log4j = {
  root {
    debug()
  }
}

This will enable and send all log to standard out.

Further refining requires studying grails logging in more detail.
