      Description

      The Variant Plugin (https://github.com/jenkinsci/variant-plugin/) is not working properly when you specify `requiredClasses` and one of them do not exists. There are two observed situations.

      • If the annotated class extends the non existent class this exception is thrown:

        This is due to the fact that Guice is not treating it as optional.
