How to filter test resources?

[Toto Laricot]

HI,

I have a file in src/test/resources/META-INF that I'd like to be filtered
before being copied to target/test-classes/META-INF.
I added this to my POM:

   <filters>
     <filter>src/main/filters/dev-env.properties</filter>
   </filters>
   <resources>
     <resource>
       <directory>src/test/resources/META-INF</directory>
       <filtering>true</filtering>
     </resource>
   </resources>

But the file is copied without being filtered. Filterring works fine for
files under src/main/resources.

Any idea?

Thanks,

Theo.
