Javadoc aggregation and multi-module

[Julien HENRY]

Hi,

My layout is as this :

myProject
   |-> pom.xml
   |-> commons-tests
              |->src
                    |->main
                          |->java
                                |-> my common JUnit tests
  |-> module 1 (depend on commons-test with scope=test)
  |-> module 2 (depend on commons-test with scope=test)

I have configured Javadoc plugin, with aggregate=true. But in my Javadoc, I 
have also commons-tests Javadoc, and I don't want it with main application. 
It's the same problem with source Xref and test source Xref: Commons-tests 
sources are with source Xref and not with test source Xref.
How can I tell to Maven that Java classes in commons-tests/src/main/java are 
tests ?

Thanks

Julien
