Does it support custom AST transformations?
A. Custom Ast transforms are supported and will be picked up from the project classpath during a build. If you wish to define and consume transforms within the same project, there is a restriction: the transform must be written in Java (not groovy) and it cannot have dependencies on groovy source in that same project. This restriction exists because Eclipse does not have a notion of separate source folders that can be separately compiled – in eclipse the source within all source folders is compiled together.
