Multiline Strings in Java 11

This past weekend I had an idea of using an Annotation Processor to convert comments into multiline strings in Java 11.

/**
SELECT Name, PhoneNumber
  FROM Event, Volunteer
 WHERE Event.ID = ${id}
   AND Volunteer.City = ${city}
 */
@Multiline
String template = "";

// ... is transformed at compile-time into...
String template = ""
    + "SELECT Name, PhoneNumber       "
    + "  FROM Event, Volunteer        "
    + " WHERE Event.ID = ${id}        "
    + "   AND Volunteer.City = ${city}";

I came up with something close. Check it out on GitHub: github.com/taeber/java-multiline
