local challenge: solution doesn't work for gradle task

treehouse/prepareSubmission doesn't work for this solution, even though it should. I've tried several other formats of lambda function , none of them worked

public static void printChipmunksDeclaratively(List<String> chipmunks) {
    // Print out each of the chipmunks using the forEach method on Iterable
    chipmunks.forEach(
      (String str) -> {
        System.out.println(str);
      });
  }

Fine, it just needed a concatenated exclamation point.

public static void printChipmunksDeclaratively(List<String> chipmunks) {
    // Print out each of the chipmunks using the forEach method on Iterable
    chipmunks.forEach(str -> System.out.println(str + "!"));
  }
