HTTP_MODELS - Jackson annotated data classes to represent the schema objects defined in the input.

CONTROLLERS - Spring / Micronaut / Ktor HTTP controllers for each of the endpoints defined in the input.

CLIENT - Simple http rest client.

QUARKUS_REFLECTION_CONFIG - This options generates the reflection-config.json file for quarkus integration projects

EXCLUDE_READ_ONLY - Exclude readOnly properties and honour requiredness of retained writeOnly properties

EXCLUDE_WRITE_ONLY - Exclude writeOnly properties and honour requiredness of retained readOnly properties

X_EXTENSIBLE_ENUMS - This option treats x-extensible-enums as enums

JAVA_SERIALIZATION - This option adds Java Serializable interface to the generated models

QUARKUS_REFLECTION - This option adds @RegisterForReflection to the generated models. Requires dependency "'io.quarkus:quarkus-core:+"

MICRONAUT_INTROSPECTION - This option adds @Introspected to the generated models. Requires dependency "'io.micronaut:micronaut-core:+"

MICRONAUT_REFLECTION - This option adds @ReflectiveAccess to the generated models. Requires dependency "'io.micronaut:micronaut-core:+"

MICRONAUT_SERDEABLE - This option adds @Serdeable to the generated models. Requires dependency "'io.micronaut.serde:micronaut-serde-jackson:+"

INCLUDE_COMPANION_OBJECT - This option adds a companion object to the generated models.

NON_NULL_MAP_VALUES - This option makes map values non-null. The default (since v15) and most spec compliant is make map values nullable

FAULT_TOLERANT_ENUMS - This option adds an UNRECOGNIZED enum entry as a fallback for unmapped values, preventing deserialization exceptions. If jackson is used, the deserialization option **READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE** will need to be enabled as well

FAULT_TOLERANT_OPEN_ENUMS - This option converts the "open enum" pattern (an anyOf combining a string enum with an open type: string) into a fault-tolerant enum, i.e. an enum carrying the declared values plus an UNRECOGNIZED fallback, instead of collapsing the type to a plain String. Behaves like FAULT_TOLERANT_ENUMS for the affected enums

DATETIME_AS_INSTANT - Use Instant as the datetime type. Defaults to OffsetDateTime

DATETIME_AS_LOCALDATETIME - Use LocalDateTime as the datetime type. Defaults to OffsetDateTime

DATETIME_AS_OFFSETDATETIME - Use OffsetDateTime as the datetime type. Default for Jackson

BYTE_AS_STRING - Ignore string format byte and use String as the type

BYTE_AS_BYTEARRAY - Use ByteArray as the byte type. Default

BINARY_AS_STRING - Ignore string format binary and use String as the type

BINARY_AS_BYTEARRAY - Use ByteArray as the binary type. Default

URI_AS_STRING - Ignore string format uri and use String as the type

URI_AS_URI - Use java.net.URI as the uri type. Default

UUID_AS_STRING - Ignore string format uuid and use String as the type

UUID_AS_UUID - Use java.util.UUID as the uuid type. Default

DATE_AS_STRING - Ignore string format date and use String as the type

DATE_AS_LOCALDATE - Use java.time.LocalDate as the date type. Default for Jackson

DATE_AS_KOTLINXLOCALDATE - Use kotlinx.datetime.LocalDate as the date type. Default for kotlinx.serialization

DATETIME_AS_STRING - Ignore string format date-time and use String as the type

BYTEARRAY_AS_INPUTSTREAM - Use InputStream as ByteArray type. Defaults to ByteArray

ANY_AS_JSONELEMENT - Use kotlinx.serialization.json.JsonElement for untyped (any) schemas and JsonObject for untyped objects. Requires the KOTLINX_SERIALIZATION serialization library. Defaults to Any

ANY_AS_ANY - Use Any as the untyped (any) type. Default

SUSPEND_MODIFIER - This option adds the suspend modifier to the generated client functions (only for OpenFeign clients)

SPRING_RESPONSE_ENTITY_WRAPPER - This option adds the Spring-ResponseEntity generic around the response to be able to get response headers and status (only for OpenFeign clients).

SPRING_CLOUD_OPENFEIGN_STARTER_ANNOTATION - This option adds the @FeignClient annotation to generated client interface

GROUP_BY_TAG - This option groups clients based on the first tag rather than paths

OKHTTP_NON_NULL_RESPONSE_PAYLOADS - This option makes ApiResponse.data non-null. Responses declared with a body must return one: a missing body, or one that deserializes to null, throws ApiException. An operation that declares both a body response and an empty success response (e.g. 200 and 204) throws on the empty success. Binary responses return an empty ByteArray for an empty body (only for OkHttp clients)

RESPONSE_MEDIA_TYPE_FUNCTIONS - This option adds, for each operation whose success responses declare a different JSON schema per media type, one function per media type. The function always sends that media type as the Accept header and returns that schema's type instead of JsonNode. Its name is the operation's function name plus the media subtype, e.g. getItemsVndCustomJson for application/vnd.custom+json (only for OkHttp, OpenFeign and Spring HTTP Interface clients)

DYNAMIC_BASE_URL - This option makes ApiConfiguration.basePath empty, allowing you to set the base URL at runtime (only for Ktor clients)

OPENAPI_BEARER_AUTHENTICATION - Adds operation-specific Bearer token helpers for OpenAPI HTTP Bearer security schemes

OPENAPI_OAUTH2_AUTHENTICATION - Adds operation-specific OAuth2 access-token helpers that pass required scopes to a caller-provided token provider

SUSPEND_MODIFIER - This option adds the suspend modifier to the generated controller functions

AUTHENTICATION - This option adds the authentication parameter to the generated controller functions

GROUP_BY_TAG - This option groups controllers based on the first tag rather than paths

COMPLETION_STAGE - This option makes generated controller functions have Type CompletionStage (works only with Spring Controller generator). Can be overridden per operation using the OpenAPI extension x-async-support: true|false

SSE_EMITTER - This option makes generated controller functions have Type SseEmitter (works only with Spring Controller generator)

ADD_FILE_DISCLAIMER - This option adds a disclaimer to the generated files.

ADD_GENERATED_ANNOTATION - Annotate generated types and top-level functions with javax.annotation.processing.Generated.
