Yes, build-helper is there for legacy build. However, if a build is

"mavenized", I see no need to have more than one primary source trees and
adding a generated source tree the project , shoud be done by the
generated source plugin
itself.
Well here's why it should be supported. I develop all my applications
using AndroMDA (with a maven2 build, we previously used maven1). During
the build, we generate sources from one "mda" module (this module
contains the model of the application) into all other modules (each
project has about 5 to 6 submodules).
Generating source from the same model for each module wouldn't be time
efficient (among other things), so its not possible to have the plugin
add the source directory to each module because the andromda plugin
isn't run for each module.. So in this case it makes sense to allow the
pom.xml to have the multiple source directories specified. For now I
created another simple plugin which adds the generated source to each
module, however it would be much easier and clearer if multple source
directories could be specified in the pom.
For now, i dont see a way out until at least 2.1, if it supports
multiple main source trees ;-)
That's my point, it doesn't work now, but it *should* support multiple
source directories,.

I completely agree. If anything, generated source will become
more and
more common as time goes on, the pom really should support multiple
sourceDirectory elements (its much cleaner and clearer than having to
use a plugin for it).
