Description

When Error Prone is used, its UnncessaryFinal bug pattern fails on the generated HttpInterfacesAbstractConfigurator, because it needlessly marks its sole constructor parameter as final.

openapi-generator version

v7.24.0

OpenAPI declaration file content or url

openapi.yaml

Generation Details

config.json

Steps to reproduce

• in a directory X, create openapi.yaml and config.json with the contents as above
• from within X, run docker run --rm -v .:/local openapitools/openapi-generator-cli:v7.24.0 generate --strict-spec true --input-spec /local/openapi.yaml --generator-name spring --config /local/config.json --output /local/output
• open .\output\src\main\java\org\openapitools\configuration\HttpInterfacesAbstractConfigurator.java

actual: final on the constructor parameter

expected: no final on the constructor parameter

Suggest a fix

Reproduce the issue with the linked openapi.yaml and config.json using the documented Docker command, then inspect the generated HttpInterfacesAbstractConfigurator.java under the Spring output path. Trace that generated constructor back to the Spring generator template and verify that the resulting parameter no longer triggers Error Prone's UnnecessaryFinal pattern.
