Пакет maven2-plugin-resources: Информация

The Resources Plugin handles the copying or transfering of
project resources to the output directory. Resources are
categorized into two: main resources and test resources.
The difference is that the main resources are the resources
associated to the main code while teh test resources are
that of the test code.
This, thus, allows the separation of resources of the main
code (what your plugin actually does) and its unit tests.
