Configuration on demand can cause problems

[dellisd]

We have a check to see if the plugin is applied to all feature modules.

With configuration on demand enabled, the feature modules may (and likely would) not be configured since the base module does not explicitly declare any dependency on the feature modules. This leads to the check failing, even when the plugin is actually being applied correctly.

Fixing this will be a prerequisite for #35.

We'll probably have to publish the partial lockfiles as build artifacts and add feature modules as a dependency of the base module in a custom configuration.. or something.
