A property with name annotations produces the following rule:

get-annotations =
  get-property(|NablProp_annotations())

which is already defined in the Stratego library, so it causes the following error during the build:

stratego.jvm.helper:
  [java] error: redefining external definition: get-annotations
  [java] giving-up
