(Quick Reference)
                create-pom
Purpose
The 
create-pom creates a POM file for the current application allowing it to be built with Maven.
Examples
grails create-pom org.mycompany
Description
The 
create-pom command will generate a 
pom.xml file usable by Maven for the current Grails application.
Running 
mvn package will build the project. To enable the 'grails' command to read the POM you can modify 
BuildConfig.groovy to use the POM and resolve dependencies from your Maven local cache:
grails.project.dependency.resolution = {
    …
    pom true
    repositories {
        …
        mavenLocal()    
    }
}
