org.apache.maven.plugins:maven-resources-plugin 2.7

The Resources Plugin handles the copying of project resources to the output directory. There are two different kinds of resources: main resources and test resources. The difference is that the main resources are the resources associated to the main source code while the test resources are associated to the test source code. Thus, this allows the separation of resources for the main source code and its unit tests.
