Swagger Core

NOTE: If you're looking for Swagger Core 1.5.X and OpenAPI 2.0, please refer to 1.5 branch.

NOTE: Since version 2.1.7, Swagger Core also supports the Jakarta namespace. There are a parallel set of artifacts with the -jakarta suffix, providing the same functionality as the unsuffixed (i.e.: javax) artifacts. Please see the Wiki for more details.

NOTE: Since version 2.2.0 Swagger Core supports OpenAPI 3.1; see this page for details

Swagger Core is a Java implementation of the OpenAPI Specification. Current version supports JAX-RS2 (javax and jakarta namespaces).
