CONFIG OPTIONS

These options may be applied as additional-properties (cli) or configOptions (plugins). Refer to configuration docs for more details.

OptionDescriptionValuesDefault
additionalEnumTypeAnnotationsAdditional annotations for enum type(class level annotations)null
additionalModelTypeAnnotationsAdditional annotations for model type(class level annotations). List separated by semicolon(;) or new line (Linux or Windows)null
additionalOneOfTypeAnnotationsAdditional annotations for oneOf interfaces(class level annotations). List separated by semicolon(;) or new line (Linux or Windows)null
allowUnicodeIdentifiersboolean, toggles whether unicode identifiers are allowed in names or not, default is falsefalse
apiPackagepackage for generated api classesorg.openapitools.client.api
artifactDescriptionartifact description in generated pom.xmlOpenAPI Java
artifactIdartifactId in generated pom.xml. This also becomes part of the generated library's filenameopenapi-java-client
artifactUrlartifact URL in generated pom.xmlhttps://github.com/openapitools/openapi-generator
artifactVersionartifact version in generated pom.xml. This also becomes part of the generated library's filename. If not provided, uses the version from the OpenAPI specification file. If that's also not present, uses the default value of the artifactVersion option.1.0.0
bigDecimalAsStringTreat BigDecimal values as Strings to avoid precision loss.false
booleanGetterPrefixSet booleanGetterPrefixget
camelCaseDollarSignFix camelCase when starting with $ sign. when true : $Value when false : $valuefalse
configKeyConfig key in @RegisterRestClient. Default to none.null
containerDefaultToNullSet containers (array, set, map) default to nullfalse
dateLibraryOption. Date library to use
joda
Joda (for legacy app only)

Legacy java.util.Date
java8-localdatetime
Java 8 using LocalDateTime (for legacy app only)
java8
Java 8 native JSR310 (preferred for jdk 1.8+)

disallowAdditionalPropertiesIfNotPresentIf false, the 'additionalProperties' implementation (set to true by default) is compliant with the OAS and JSON schema specifications. If true (default), keep the old (incorrect) behaviour that 'additionalProperties' is set to false by default.
false
The 'additionalProperties' implementation is compliant with the OAS and JSON schema specifications.
true
Keep the old (incorrect) behaviour that 'additionalProperties' is set to false by default.
true
discriminatorCaseSensitiveWhether the discriminator value lookup should be case-sensitive or not. This option only works for Java API clienttrue
ensureUniqueParamsWhether to ensure parameter names are unique in an operation (rename parameters that are not).true
enumPropertyNamingNaming convention for enum properties: 'MACRO_CASE' and 'legacy'MACRO_CASE
enumUnknownDefaultCaseIf the server adds new enum cases, that are unknown by an old spec/client, the client will fail to parse the network response.With this option enabled, each enum will have a new case, 'unknown_default_open_api', so that when the server sends an enum case that is not known by the client/spec, they can safely fallback to this case.
false
No changes to the enum's are made, this is the default option.
true
With this option enabled, each enum will have a new case, 'unknown_default_open_api', so that when the enum case sent by the server is not known by the client/spec, can safely be decoded to this case.
false
fullProjectIf set to true, it will generate all files; if set to false, it will only generate API files. If unspecified, the behavior depends on whether a project exists or not: if it does not, same as true; if it does, same as false. Note that test files are never overwritten.
generateBuildersWhether to generate builders for modelsfalse
generateConstructorWithAllArgswhether to generate a constructor for all argumentsfalse
groupIdgroupId in generated pom.xmlorg.openapitools
helidonVersionHelidon complete version identifier or major version number. The specified exact Helidon release or, if specified as a major version the latest release of that major version, is used in the generated code.Highest released version.
hideGenerationTimestampHides the generation timestamp when files are generated.false
ignoreAnyOfInEnumIgnore anyOf keyword in enumfalse
implicitHeadersSkip header parameters in the generated API methods using @ApiImplicitParams annotation.false
implicitHeadersRegexSkip header parameters that matches given regex in the generated API methods using @ApiImplicitParams annotation. Note: this parameter is ignored when implicitHeaders=truenull
invokerPackageroot package for generated codeorg.openapitools.client
legacyDiscriminatorBehaviorSet to false for generators with better support for discriminators. (Python, Java, Go, PowerShell, C# have this enabled by default).
true
The mapping in the discriminator includes descendent schemas that allOf inherit from self and the discriminator mapping schemas in the OAS document.
false
The mapping in the discriminator includes any descendent schemas that allOf inherit from self, any oneOf schemas, any anyOf schemas, any x-discriminator-values, and the discriminator mapping schemas in the OAS document AND Codegen validates that oneOf and anyOf schemas contain the required discriminator and throws an error if the discriminator is missing.
