/**
* "assemble" is an incremental task but with a twist. Because it can be costly to determine if any
* of the class files generated in the previous phase is new or not, we just don't do that and always
* return "null" for both input and output checksums, which would cause that task to always be rerun.
* However, we are depending on Kobalt's cascading incremental management to skip up whenever appropriate:
* whenever a previous incremental task was a success, all following incremental tasks are automatically
* skipped.
