Sorry for the late reply.

I am not entirely sure the jars need to be deployed to a repo. You  
aren't going to eliminate the need to actually install grails on disk.

Absolutely.

Do you have a use case for this?

Would be nice, but I think it's around the wrong way. I don't think  
Grails should have to know about Maven: Maven should know about Grails.

What's the benefit here?

‘grails compile’ may introduce new magic in the future which we would  
potentially miss out on. I don't see any benefit of not using grails'  
own compile mechanism.

You can do this now in a roundabout way, have a look at the ldap plugin.

Again, why? I would rather be 100% sure that when I build the WAR  
with Maven I get the exact same war I would have got with ‘grails war’

p.s. I am not trying to be negative here, I desperately want this  
functionality. I just want to make sure the right problems are being  
solved.
