- how to deal with resolution from different places like local/remote/workspace
- how to incorporate the metadata processor to start with
- create a hook to programmatically configure the test
- create a plugin processor
- directory
- jar
- hooks for loading

- I could make an annotation that marked another class as its plugin discoverer, I could just add it to
