Does this plugin copy jar file to WEB-INF/lib?

[thinkkevin]

I have a Grails 2.0.3 project with maven. I found an interesting phenomenon that this plugin (I guess, as I didn't find the cause) might copy other jar files to WEB-INF/lib after mvn package done.

For those machines which didn't config grails, the might happens. For those machines which configs grails 2.0.3, this doesn't happen.

So I come to ask if this plugin has logic to check env variable like GRAILS_HOME?

The issue I encountered that when I tried to do maven install, it introduced two versions of slf4j, which leads to deployment error.
