Amigos, me deparei com um problema que não havia enfrentado antes.
Ao tentar rodar uma aplicação recém criada, o mesmo não executa.
Segue a linha do erro:

Error Failed to resolve dependencies (Set log level to 'warn' in BuildConfig.groovy for more information):

- org.grails.plugins:tomcat:2.2.0

..........................

Segue o trecho do meu arquivo BuildConfig.groovy.

grails.servlet.version = "2.5" // Change depending on target container compliance (2.5 or 3.0)
grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"

grails.project.target.level = 1.6
grails.project.source.level = 1.6
