The groupId de.cuioss.sheriff.api is abandoned. Its only release, 1.0.0, was published accidentally on 2026-07-12 from a project still in pre-1.0 development and was never intended for use. The project now publishes under de.cuioss.sheriff.gateway and has restarted its version line at 0.1.0-SNAPSHOT; there is no 1.x release under the new coordinates. Update the groupId to de.cuioss.sheriff.gateway and select a version once one is released. Java packages moved from de.cuioss.sheriff.api.. to de.cuioss.sheriff.gateway.. as well; the gRPC wire service paths are unchanged.
