com.guidedbyte.openapi-modelgen A comprehensive Gradle plugin for generating Java DTOs from multiple OpenAPI specifications with enhanced features: ## Requirements • Java 17+ • Gradle 8.0+ • OpenAPI Generator 7.14.0+ (automatically managed) ## Features • Multi-spec support with individual task generation • Lombok annotation integration (@Data, @Builder, @SuperBuilder, etc.) • Custom Mustache template support with precedence resolution • Template variable expansion (nested variables like {{currentYear}} in {{copyright}}) • Incremental build support for optimal performance • Configuration validation with detailed error reporting • Parallel template processing for large template sets • Content-based template change detection using SHA-256 hashing ## Usage Examples ### Basic Configuration ```groovy plugins { id 'com.guidedbyte.openapi-modelgen' version '1.0.0' } openapiModelgen { defaults { outputDir "build/generated-sources/openapi" modelNameSuffix "Dto" generateModelTests false validateSpec true } specs { pets { inputSpec "src/main/resources/openapi-spec/pets.yaml" modelPackage "com.example.model.pets" } orders { inputSpec "src/main/resources/openapi-spec/orders.yaml" modelPackage "com.example.model.orders" } } } ``` ### Advanced Configuration ```groovy openapiModelgen { defaults { outputDir "build/generated-sources/openapi" templateDir "src/main/resources/openapi-templates" configOptions([ dateLibrary: "java8", serializationLibrary: "jackson", useBeanValidation: "true", hideGenerationTimestamp: "true" ]) templateVariables([ copyright: "Copyright © {{currentYear}} {{companyName}}", currentYear: "2025", companyName: "My Company Inc." ]) globalProperties([ skipFormModel: "false", generateAliasAsModel: "true" ]) } specs { pets { inputSpec "specs/pets-v1.yaml" modelPackage "com.example.pets.v1.model" configOptions([ additionalModelTypeAnnotations: "@lombok.Data;@lombok.experimental.SuperBuilder" ]) } } } ``` Command Line Options: All configuration options can be overridden via command line: • --model-package=com.example.model • --output-dir=build/custom-output • --template-dir=custom-templates • --model-name-suffix=Entity • --validate-spec • --generate-model-tests • --generate-api-docs Task Generation: • generateOpenApiDtosForPets - Generate DTOs for pets specification • generateOpenApiDtosForOrders - Generate DTOs for orders specification • generateOpenApiDtosAll - Generate DTOs for all specifications Dependencies: The plugin automatically detects and works with any OpenAPI Generator version provided by your configuration management (corporate plugins, etc.). If no version is found, it falls back to the tested default version 7.14.0. The plugin also automatically adds required dependencies including Lombok, Jackson, Spring Boot validation, and JSR-305 annotations. Template Customization: Place custom .mustache templates in your template directory to override plugin defaults. Template resolution follows precedence: user templates > plugin templates > OpenAPI generator defaults.
