properties file in EE app's META-INF

How do I manage to put my hibernate.properties file in the ear's META-INF folder?
Idea won't let me add any non-xml resources in the "J2EE Application Module Settings".

I know I can just add the properties in the persistence.XML (that's what I actually did).
Also I can build and deploy using ant (that's what I am also going to do).

I think Idea should simply include everything that is inside the META-INF folder into the build.
