Do you touch upon refactoring in your
recepies or is green field development
as a departure?
I guess that depends on the individuals requirements for refactoring.
I find at times there are components and services in my application that are difficult to maintain, or impossible to add new desired business features out-of-the-box.
This is where extending the tool-set with aspectJ, CDI Interceptors, or using JVM languages like Groovy and scala etc, help to refactor using a new tool in the mix.
What was really troublesome is getting the build (Maven and Gradle) to integrate well with several tools in the mix.
But the recipe show how to integrate into an existing project, not just a green field project.
