Play 2.4-RC5: ReflectionsException: Scanner SubTypesScanner was not configured

[Guofeng Zhang]

Hi,

I have the following invocation in my code:

   Classpath.getTypesAnnotatedWith(application, "models", Entity.class)

when it is executed, it throws:

org.reflections.ReflectionsException: Scanner SubTypesScanner was not configured

     org.reflections.Store.get(Store.java:58)

     org.reflections.Store.get(Store.java:70)

     org.reflections.Store.getAll(Store.java:97)

     org.reflections.Reflections.getAllAnnotated(Reflections.java:423)

     org.reflections.Reflections.getTypesAnnotatedWith(Reflections.java:384)

     org.reflections.Reflections.getTypesAnnotatedWith(Reflections.java:370)

     play.libs.Classpath.getTypesAnnotatedWith(Classpath.java:44)

     ......

I change Classpath.getReflections() the following from

 .setScanners(new TypeElementsScanner(), new TypeAnnotationsScanner())) ;

to

 .setScanners(new TypeElementsScanner(), new TypeAnnotationsScanner(), new SubTypesScanner())) ;

The above invocation worked.

Is it a bug in Classpath.getReflections() or the way I invoked getTypesAnnotatedWith improperly?

Thanks for your help.

the same exception using just released 2.4.0

Refelctions 0.99 requires SubTypeScanner to be set for getTypesAnnotatedWith.
