Adding Ant targets to the pre-process pipeline

Every step in the pre-process pipeline defines an extension point before and after the step, to allow plug-ins to integrate additional processing. This allows a plug-in to insert a new step before any pre-processing step, as well as before or after the entire preprocess pipeline.

The group of preprocessing steps defines extension points before and after the full preprocessing chain.

depend.preprocess.pre
Preprocessing pre-target; extending this target runs your Ant target before the full preprocess routine begins.
depend.preprocess.post
Preprocessing post-target; extending this target runs your Ant target after the full preprocess routine completes.

In addition, there are extension points to execute an Ant target before individual preprocessing steps.

depend.preprocess.clean-temp.pre
Clean temp pre-target
depend.preprocess.gen-list.pre
Generate list pre-target
depend.preprocess.debug-filter.pre
Debug and filter pre-target

Example

The following feature adds "myAntTargetBeforeChunk" Ant target to be executed before the chunk step in preprocessing. It assumes that an Ant file defining that target has already been integrated.

<plugin id="com.example.extendchunk">
  <feature extension="depend.preprocess.chunk.pre" value="myAntTargetBeforeChunk"/>
</plugin>

When integrated, the Ant target "myAntTargetBeforeChunk" will be added to the Ant dependency list so that it always runs immediately before the Chunk step.
