nested generic types

It is now possible to create type mappings with nested generics types. Here are a few examples:

openapi-processor-mapping: v3

  package-name: generated

    - type: Foo => java.util.Map<java.lang.String, java.util.List<java.lang.String>>

        - content: application/json => java.util.Map<java.lang.String, java.lang.String>

        - content: application/json => java.util.Map<java.lang.String, java.util.List<java.lang.String>>

This is useful to map an OpenAPI dictionary description using additionalProperties to a proper java map type:

# a schema the defines a dictionary with string keys and string values
    type: object
      type: string

annotation mapping allows class parameter

annotation mapping now accepts a java class type as parameter. It is possible to add a mapping like this:

openapi-processor-mapping: v3

    - type: string:foo @ io.oap.Annotation (value = io.oap.Bar.class)

improved validation output

schema validation by the internal parser has simpler & better output based on the JSON schema basic output format. It is not perfect but it is getting better.

It will provide better help on where the error is, but it may report multiple ambiguous errors.

If a schema property uses anyOf or oneOf and all possibilities don’t match (e.g. because there is a spelling error) the validator can’t know which one was meant and complains about all of them.

An example:

the error the value does not validate against the 'false' schema at instance …​ usually means that a property has a spelling error.

If the OpenAPI allows a $ref at the same location the validator reports a second error should have a property '$ref' at instance …​ because a reference object must have a $ref property.
