How to set a custom Maven repository manager in Grape

I would like to use grape to install a library by command-line. So I've issued the command:

grape -V install org.apache.derby derby 10.5.3.0

Grape should use the Maven repository located at http://127.0.0.1:8081/artifactory/webapp/home.html. How can I configure it?

After enabling the verbose mode, I see in the logs:

                tried http://repository.codehaus.org/org/apache/derby/derby/10.5.3.0/derby-10.5.3.0.pom

So I tried to update the file org/apache/ivy/core/settings/ivysettings-public.xml in the jar /opt/groovy-1.7.2/lib/ivy-2.1.0.jar for adding a "root" attribute that points to the above repository, but Grape seems to not be able to get the change.

just add a grapeConfig.xml to your grape home dir
