Grails run-app "The name of the resource source must contain at least one character"

When I want to start the grails application using " grails run-app", I get the following message:

| Running Grails application
| Error 2014-02-25 10:28:12,493 [localhost-startStop-1] ERROR context.GrailsContextLoader  - Error initializing the application: Property source name must contain at least one character

I am using Grails 2.3.4 on a clean system ( Mac OS X).

If this is useful, here is my .bash_proifile

export JAVA_HOME=/Library/Java/Home
export PATH="$PATH:$JAVA_HOME/bin"
GRAILS_HOME=/Applications/grails-2.3.4; 
export GRAILS_HOME
PATH=$GRAILS_HOME/bin:$PATH; 
export PATH

The application works fine on 4 other computers.
