When using the Grails Maven plugin, Grails' dependency resolution mechanics are disabled as it is assumed that you will manage dependencies via Maven's pom.xml file.

However, if you would like to continue using Grails regular commands like run-app, test-app and so on then you can tell Grails' command line to load dependencies from the Maven pom.xml file instead.

To do so simply add the following line to your BuildConfig.groovy:

grails.project.dependency.resolution = {
 	pom true
	..
}

The line pom true tells Grails to parse Maven's pom.xml and load dependencies from there.
