 We once had a document that Vincent and I agreed upon and I was about to
 implement it and then I disappeared for 8 months so it never came to pass.

 So I guess it's important to figure out what people are using properties
 files for and see if we can't incorporate it all into the POM. Or if we do

  is the DefaultExpressionEvaluator, which is a local variable within the
  implementation of the BasicComponentConfigurator. This ExpressionEvaluator
  simply returns the expression itself as the resolved value, which adds
  very little value to the container. Things like ${project.build.resources}
  are not resolved, and result in a type mismatch for the member injection.

  We need a replacement for DefaultExpressionEvaluator that is capable of

the mapping mechanism by which parameters are taken from the REST side of the application and mapped into a method call within a given Plexus component. Whether that be the core Nexus application or a component provided by a plugin.

At the very least in the short term the resource needs to know how to look up the component that is required to perform the work. This needs to be made simple, for the time being we can write and test plugins working in the same realm until we get complete isolation...
