Since resources don't have any particular extension, they need to be explicitly marked as being resources. In addition, since it is possible that a user might want to explicitly treat a non-compilable .java file (as an example) as a resource, it's important that the JavacPlanner not use (only) the extension to determine the type of a source.

This change uses subclasses of Sources to differentiate between sources of different types/extensions, and moves Sources off of their distinguished place on Target, and into the configurations list.

  • Make Sources abstract, with an extensions property, which could become a default filter on globs for instances of a Sources subclass, but it is currently only used for validation of literal files lists
  • Move Sources to the configurations list for a target, which allows for uniform selection of configuration by type
  • Add a helper to Target to match configuration by type
  • Add ResourcesPlanner to provide a Classpath for Resources
  • Add an example java project that consumes resources

One downside of this change is that every useful Target will have at least one configurations member: I think we're going to want to lower the friction on defining configurations as close to zero as possible, perhaps by having them defined as a repeated parameter on the end of the Target constructor, rather than in a nested list?
