Why does SpringOpenApi3.0 still need io.swagger.models dependency?

[星小梦]

Project current dependencies

io\swagger\core\v3\swagger-models\2.1.2\swagger-models-2.1.2.pom

io\swagger\core\v3\swagger-annotations\2.1.2\swagger-annotations-2.1.2.pom

Use OpenApi3.0 annotations, do you still need

io/swagger/models/Swagger: Is the 1.5.X version of the dependency package?

In the Maven warehouse (https://mvnrepository.com/artifact/io.swagger/swagger-models), you can see that it is migrated to the new warehouse location

Note: This artifact was moved to:

io.swagger.core.v3 » swagger-models

So, I want to ask io\swagger\core\v3\swagger-models\2.1.2 Is the dependency package not the migration optimized version of io.swagger:swagger-models: 1.6.2? Why rely on the predecessor of models? swagger -annotation problem is the same

[星小梦]

So, why does the 2.1.5 version need to depend on the 1.6.2 version?

Why is the annotation @Schema of swagger2.0 (OpenApi3.0 specification) added to the model data field, no description information is output, and it cannot be hidden, and other annotations have attributes that do not work? This is because swagger2.0 is not perfect? Currently in the testing and development stage?
