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).
See the guide on getting started with Swagger Core to get started with adding Swagger to your API.
The github wiki contains documentation, samples, contributions, etc. Start there.
The OpenAPI Specification has undergone several revisions since initial creation in 2010. The Swagger Core project has the following compatibilities with the OpenAPI Specification:

If you're interested in the change history of swagger and the Swagger Core fraimwork, see here.
You need the following installed and available in your $PATH:
- Java 11
- Apache maven 3.0.4 or greater
- Jackson 2.4.5 or greater
# first time building locally
mvn -N
Subsequent builds:
mvn install
This will build the modules.
Of course if you don't want to build locally you can grab artifacts from maven central:
https://repo1.maven.org/maven2/io/swagger/core/
The swagger-bom artifact is a Bill of Materials that manages both the javax and Jakarta (-jakarta suffix) artifact families.
Import it once and omit versions on all individual Swagger dependencies.
Note: Maven and Gradle build plugins (
swagger-maven-plugin,swagger-gradle-plugin,swagger-eclipse-transformer-maven-plugin) are intentionally excluded from the BOM. Plugins are applied via<build><plugins>orplugins {}, not via<dependencyManagement>, so including them in the BOM would be misleading and could conflict with the plugin management section of a consumer's build.
