Check, if all classes in project have a specific annotation

My current situation: I want to write a test that checks, if all my files with "Service" in the name have the "@Valid" Annotation. I tried researching it but could not find anything.

The Java Reflection API can be used to check the annotations of a class.

E.g. the following code prints the name and value of each class annotation of type MyAnnotation.

Class aClass = TheClass.class;
Annotation[] annotations = aClass.getAnnotations();

for(Annotation annotation : annotations){
    if(annotation instanceof MyAnnotation){
        MyAnnotation myAnnotation = (MyAnnotation) annotation;
        System.out.println("name: " + myAnnotation.name());
        System.out.println("value: " + myAnnotation.value());
    }
}

The comment by Lino shows how to find all classes in the current classpath.
