spring boot 2.2 cannot serve swagger-resources when used with springdoc-openapi

问题

https://www.dariawan.com/tutorials/spring/documenting-spring-boot-rest-api-springdoc-openapi-3/

According to this, using springdoc openapi dependencies should pull in swagger3

I am using

        <dependency>
        <groupId>org.springdoc</groupId>
        <artifactId>springdoc-openapi-ui</artifactId>
        <version>1.2.15</version>
    </dependency>
    <dependency>
        <groupId>org.springdoc</groupId>
        <artifactId>springdoc-openapi-webmvc-core</artifactId>
        <version>1.2.15</version>
    </dependency>

The swaggerui page looks for swagger-resouces which end in 404

MyErrorController.handleError:30 - ErrorController {timestamp=Wed Dec 11 13:56:37 CST 2019, status=404, error=Not Found, message=No message available, path=/swagger-resources}

I see these in dependencies

 |  \- org.webjars:webjars-locator:jar:0.37:compile
