Remove this unused import 'com.cartrust.comregistraiton.organiozation.model.DocumentState.UPLOADED'
  • steps to reproduce

It seem related to the enum value “UPLOADED” if I refactor the value to “UPLOADED_YEAH” the error disappears. Of course it was used after the refactoring too.

Other enum values from the same enum are not shown as errors:

import static com.cartrust.registration.organization.model.DocumentState.MISSING;
import static com.cartrust.registration.organization.model.DocumentState.UPLOADED;
import static com.cartrust.registration.organization.model.DocumentState.WAITING_FOR_NOTIFICATION;
import static com.cartrust.registration.organization.model.DocumentState.WAITING_FOR_UPLOAD;

Here’s the usage in the same file:

  @EventHandler
  public void on(DocumentAddedEvent event) {
    val aggregateId = event.getOwnerOrganizationId();

    organizationViewRepository.findById(aggregateId).ifPresent(
        organizationView -> {
          organizationViewRepository.save(organizationView.toBuilder()
                .businessRegistrationDocumentId(event.getDocumentId())
                .businessRegistrationState(UPLOADED)
                .build());         
        }
    );
  }
  • potential workaround

Rename enum values “UPLOADED” to something else.

P.S.: use the #bug:fault sub-category if you’re hitting a specific crash/error , or the #bug:fp sub-category for rules-related behaviour
