Use local flat file repository instead of remote maven repository

I have no experience with maven, so excuse me if this question is silly...

From another question (How does Grails handle plugin dependencies), I've learned that I can avoid the jar-hell in grails through maven repositories. But I now have the requirements that...

I already worked with a reference to a local folder for plugin resolution. This works great.

But how do I have to structure a local folder in order to use this option:

repositories {
  flatDir name:'myRepo', dirs:'/path/to/repo'
}

I mean, I could just drop the jar files to this folder, but how do I then reference those jar files? Do they have a naming schema like artifact_version.jar? Or do I have to create an XML configuration for this local repository?

Or is the effort to use a local maven repo small and maven is even already on my machine through grails?

The fact is Maven comes already with a local repository (~/.m2 on linux boxes). If you don't have access to an external repo, you just have to install your jars in the local repo, with this command

mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>

is 'jar' (without quotes) and group-id and artifact-id are either determined if it's 3rd-party library (go make a search on mvnrepository.com if you don't know them for a particular library) or you put there your group and artifact ids

EDIT : In fact, the naming scheme under the repository is for the library example version 1.2 from jexample.com is usually com/jexample/example/1.2/example-1.2.jar (groupId : com.jexample, artifactId : example, version : 1.0)
