Description

When I run the JavaSpring generator in my maven build execution from my OpenAPI definition yaml file, in the java code generated the #description value in the @Operation annotation is absent.

@Operation(
    operationId = "xxxxxx",
    summary = "xxxxxxx",
    tags = { "xxxxx" },
)

it should be:

@Operation(
    operationId = "xxxxxx",
    summary = "xxxxxxx",
    description = "xxxxxxxx",
    tags = { "xxxxx" },
)

openapi-generator version

5.4.0

OpenAPI declaration file content or url
