[Andrew Niefer <aniefer@xxxxxxxxxx>]

There are basically two places to do
this kind of processing.
As you mentioned, the customTargets.xml
postFetch or preGenerate.  I'm not sure of the details of Athena,
but I looked briefly at org.eclipse.dash.common.releng and it looks like
they deliver a customTargets.xml that gets used normally.

If Athena allows you to specify properties
that will be set before calling pde.build, then you could provide your
own customTargets.xml and set "customTargets" to point to your
own copy.  (Setting this property is one of the first things pde.build
does, which is why you need to set it before calling build.)  I would
suggest your copy then import the Athena version.  You're customTargets.xml
can have something like:

<available
property="athenaCustom"
file="${builder}/customTargets.xml"
value="${builder}/customTargets.xml"
/>
<import file="${athenaCustom}"/>
<target name="preGenerate"
>
   stuff here
overrides the preGenerate target in athenaCustom
</target>


The other place to do this is using
a customBuildCallback.xml in the plugin itself.
http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.pde.doc.user/tasks/pde_custom_callbacks.htm
The pre.build.jars target would be appropriate
place to do this work.

The decision between the two would normally
be based on how specific this processing is to the plugins.  For something
that is looking at a model file in your bundle and generating .java files
I would probably use custom call backs instead of custom targets.  Unless
every bundle (or at least a lot of them) need to do the same processing.

Not sure where / how you'd invoke that, or if we expose
that hook in PDE 
(yet). I'll copy this to dash-dev@ and to Andrew Niefer - he might have
a suggestion for how you can do this or what we need to add in Athena.
