Resolving External Annotations Is Continually Running In The Background

Since the latest update there are several background tasks that are constantly running when I open my gradle project saying "Resolving external annotations".

I even left my PC on overnight and the tasks do not complete.

There are lots of messages like this in the log

2018-10-04 18:07:15,337 [1829870] INFO - lAnnotationsRepositoryResolver - No annotations found for [org.glassfish.hk2.external:javax.inject:2.4.0-b34]
