# Project Dependencies | ||
|
||
This module is highly experimental; provides an abstract API to query project dependncies | ||
that shall be implemented by | ||
- gradle | ||
- maven | ||
- ant/nbm support | ||
At this moment, just Maven implements it and I need to validate the API design by adding | ||
the other implementations before the API is going to be published officially. In the | ||
meantime, implementation dependencies are required to access / implement the API. | ||
|
||
The code will **eventually merge** into `project.api` module and this experimental one | ||
will be deleted. | ||
