Steps to reproduce

Related issues/PRs

Suggest a fix

Start with the generated java-play-framework project/plugins.sbt and reproduce the issue using the openapi-generator CLI command and the supplied OpenAPI declaration. Trace the generator template responsible for that file and determine the supported dependency configuration. Done means the generated server can resolve its SBT dependencies and deploy without the reported Maven resolution error.
