Add URL Mapping on demand - grails

Question

My grails project has at least 20 controllers each with at least 4 methods each, and it is continuing to grow. I decided to annotate every method like this:
import enums.URLMapped
class HomeController {
#URLMapped(url="/", alias="home")
def landingPage() {
render(view: "/index")
}
}
How can I append this URL value inside the URLMapping.groovy dynamically? I could do something like:
import enums.URLMapped
import java.lang.reflect.Method
import org.apache.commons.lang.StringUtils
import org.codehaus.groovy.grails.commons.DefaultGrailsControllerClass
import org.codehaus.groovy.grails.commons.GrailsApplication
class UrlMappings {
static mappings = {
"/$controller/$action?/$id?(.$format)?"{
constraints {
// apply constraints here
}
}
// My annotation crawler/parser
for(DefaultGrailsControllerClass controller in GrailsApplication.getControllerClasses()) {
for(Method method in controller.getClazz().getDeclaredMethods()) {
if(!method.isSynthetic()) {
if(method.isAnnotationPresent(URLMapped.class)) {
URLMapped url = method.getAnnotation(URLMapped.class)
name "${url.alias()}": "${url.url()}" {
action="${method.getName()}"
controller="${StringUtils.capitalize(controller.getClazz().getSimpleName().split(/Controller/).getAt(0)}"
}
/* What I want to achieve above is this static URL:
name home: "/" {
action="landingPage"
controller="Home"
}
*/
}
}
}
}
}
}
But the problem is that static mapping is a closure and you shouldn't suppose to loop (?) inside it. So how can I add my URL? I could always put all static URL for all of our links here, it's just getting tedious to maintain.

I would strongly recommend you get rid of this idea with annotations but to divide your project into several plugins (each - a separate grails-app) tied together with gradle.
