Neil, thank you so much!
It was my inattention to bundle's imports once again that caused this issue. I added the package with the DataProvider annotation to imports and things started to work as expected.

Best regards

Does your DS component bundle import the package that contains the DataProvider 
annotation type? And does the bundle doing the introspection in Groovy code 
also import that package, from the same provider?

If these don’t match up then I would expect the getAnnotation() method to 
return null. Classloading for annotations is a little different than for normal 
classes — when something goes wrong, the JRE does not raise an exception but 
instead simply throws away the annotation metadata.

Neil

Hello,

I'm trying to annotate some methods in my DS class and then get these 
annotations from the host application. Unfortunately, when I calling 
getAnnotation() from the host it always returns null.

My annotation looks like this:
@Retention(RetentionPolicy.RUNTIME)
public @interface DataProvider {
    String optionType();
    String optionTemplate();
}

and the code which looks for DataProvider is (dont mind groovy syntax):
for (Method method : module.class.methods){
            println("method name: " + method.name)

            println("has DataProvider annotation: " + 
method.getAnnotation(DataProvider.class) )

        }
would always print null for every method in my DS, including annotated ones.

Any ideas what I'm doing wrong?

Thank you
