I found another reason Jersey could fail to find a root resource. The error message is the same, so I thought it'd be a good reason to document the root cause here in case other people stumble on it.
I have a root resource class that has the following annotations on it:
@Singleton
@Path("/helloWorld")
@Service(...) // my own custom annotation
public class MyRootResource {
...
}
This will cause the root resource scanning within Jersey to fail.
The fix is to change the order of the annotations:
@Service(...) // my own custom annotation
@Singleton
@Path("/helloWorld")
public class MyRootResource {
...
}
This works.
