I think the issue is you are building with the latest NAR plugin, but then you have a dependency on an older version of nifi-api.
Not sure how your project is setup, but try changing to nifi-api 1.9.2. If you are using a project generated from the archetype, then you may be getting nifi-api from your root pom having a parent on nifi-nar-bundles. If that is the case then use nifi-nar-bundles 1.9.2. We probably should document somewhere that the 1.3.1 NAR plugin is dependent on nifi-api 1.9.x. Not sure where the best place to do that would be.
