i have upgraded my GGTS to 3.6.3, java to 1.8 and grails to 2.4.4. I need to update log4j to 2.x or better. is there a guide somewhere that will tell me what i need to do? Just plugging the dependencies into my buildconfig.groovy doesn’t work as it leave the old log4j versions in the buildpath – i’m assuming these are default grails dependencies.
