My need is pretty basic but I could not find any clean answer to it: I simply need to be able to distribute a resource in a multi-module project.
Let us consider fo
you could use the assembly and the dependency plugins.. did you stumble over that link? http://www.sonatype.com/people/2008/04/how-to-share-resources-across-projects-in-maven/
it describes that option ..its from 2008, but maven is around for quite some time.. so I guess its more or less up to date
edit regarding comment
Another option is the maven-remote-resources-plugin.
For a more detailed example see:
http://maven.apache.org/plugins/maven-remote-resources-plugin/examples/sharing-resources.html
Since their intro speaks actually for itself, I quote (maven.apache.org)
This plugin is used to retrieve JARs of resources from remote repositories, process those resources, and incorporate them into JARs you build with Maven. A very common use-case is the need to package certain resources in a consistent way across your organization: at Apache it is required that every JAR produced contains a copy of the Apache license and a notice file that references all used software in a given project.
