I guess we can merge this after rebasing on #70

There doesn't seem to be any problem to merging this, but looking at this now, I'm not sure what this solves?

It technically doesn't solve anything since #72 ended up moving the ARQ out of the task execution. If it didn't then project couldn't be used to get the dependencies since usage of project is disallowed during task execution if configuration cache is enabled.

This PR pulls the dependencies out of Project instead of passing Project around to highlight the issue, and serve as an example of why not passing Project around is a good idea.

It also technically is good practice from a dependency perspective because these classes don't need Project; they need the classes that Project provides instances of.
