Description

Description

This error is present for jersey1 and jersey2 libraries, generator works fine and output code can be build with mvn package, however when we try to run sample with mvn jetty:run we got a long error message like this:

Validation of the application resource model has failed during application initialization.
[[FATAL] A resource model has ambiguous (sub-)resource method for HTTP method GET and input mime-types as defined by"@Consumes" and "@Produces" annotations at Java methods public javax.ws.rs.core.Response io.swagger.api.StoreApi.getInventory(javax.ws.rs.core.SecurityContext) throws io.swagger.api.NotFoundException 
and public javax.ws.rs.core.Response io.swagger.api.StoreApi.getOrderById(java.lang.Integer,javax.ws.rs.core.SecurityContext) throws io.swagger.api.NotFoundException at matching regular expression /Store.

Research direction
Investigate the generated JAX RS resource classes for ambiguous path and HTTP method annotations. The error originates from Jersey's runtime resource model validation. Look at the templates in swagger codegen (e.g., Jersey server generators) to see how paths and methods are mapped, particularly for endpoints like /Store and /User that have multiple methods with the same HTTP method and mime types. Compare with swagger specification files to ensure unique method signatures.
