Hit this recently by myself. In modern Groovy (2.5) there are @CompileStatic and @TypeChecked annotations. But, if you create new class or method node in local AST transformation and try to annotate it with those, this won't work. The reason is that code that they are implemented with local AST transformations too, and the code that detects which transformation should be applied is run before your AST transformation. More exactly, it is run in SEMANTIC_ANALYSIS phase. And you can't create local AST transformation before this phase.
Workaround that I found is to call appropriate transformation by yourself: new StaticCompileTransformation().visit([new AnnotationNode(ClassHelper.makeCached(CompileStatic), node] as ASTNode[], sourceUnit) In this case it works. Hope it'll help somebody. In more complicated cases (with different annotations) this may not work since that transformation may require specific phase and don't work in yours.
