* Along with this comes the testing strategies that make this work
* The repository model where plugins can be stored and cataloged

TODO

- dealing with processing of input and adapting GAVs before searching i.e. plugin groups in Maven and default searching
- how to deal with resolution from different places like local/remote/workspace
