#### Continuous Improvement
- Project sustainability is not just about features. Many SIGs have been working on  improving test coverage, ensuring the basics stay reliable, and stability of the core feature set and working on maturing existing features and cleaning up the backlog.

Mercury could utilize to resolve and retrieve dependencies. We need to be careful that we are using Mercury during development and production so that we don’t get in the situation where Maven 2.x is resolving differently than Mercury is. We can still leverage POMs during development but we need to make sure Mercury is doing the work.

With respect to development inside an IDE the workspace from which we would like to resolve and retrieve dependencies is a read-only local repository to Mercury...
