Resource folder not on classpath

Question

My previous question about a problem I had, led me to numerous file path changing in order to come up with an answer that caused Maven not not to work properly (apparently Maven is not fond of sub-source-folders).
I changed the project folders to adhere Maven's standard directory layout and put log4j2.xml under src/main/resources/META-INF and the problem returned.
For some reason a Folder in eclipse is not on classpath.

How do I make it work?

EDIT:
I'm using the latest m2e to manage project's build and packages.
The project (is currently) consists of several sub-projects.
The parent pom defines the different modules and Java's compiler version. The pom of the module containing the META-INF folder, states several dependencies, nothing more.

Solution

rightclick on your project -> add source folder -> select your resourcefolder. done.
