maven plugin: groups, excludeGroups priority

[Barakka]

Hello,

it's not clear to me which is the priority between the groups and
excludeGroups configuration in the maven plugin.

If i set the plugin with something like:

<groups>groupA,groupB</groups>
<excludeGroups>groupC</excludeGroups>

and a test annotated with:

@Test(groups = {"groupA","groupB","groupC"}

will the test be executed on not?

Thanks,
Riccardo.
