Problem with creating getters and setters with List

Im learning one to many mapping and this is my field for courses

 @OneToMany(mappedBy = "instructor", cascade = {CascadeType.MERGE, CascadeType.PERSIST,    CascadeType.DETACH, CascadeType.REFRESH})   private List<Course> courses;  

I have some other fields, i will update question if someone request but i think other fields and code is not important because everything is okey.

My problem is, when I go to auto generate getters and setters im getting this:

 public List<com.hibernate.demo.entity.Course> getCourses() {      return courses;   }  

As you can see for some reason, parameter for list is full package path with name of List field parameter. I can manually change it to just Course but that doesnt work after when I try to create this method.

public void add(Course tempCourse) {        if (courses == null) {          courses = new ArrayList<>();      }      courses.add(tempCourse);      }  

After manually change List parameter to Course my error for method is Cannot access com.hibernate.demo.entity.Course so that mean he is still searching for full package even I put parameter to Course. Error is on course.add(tempCourse);

Also, I created same List in Course class with Instructor paramter and everything works fine.
