SpringDoc OpenAPI swagger MergeAnnotations error

I am trying to configure OpenAPI with swagger to my existing non-spring boot application.

Spring v.5.1.8.RELEASE SpringDoc v.1.4.6 Spring-boot v.2.3.2.RELEASE

Open doc and swagger with spring mv

My application is not spring boot enable that’s why I have following dependencies in my Pom copied from article linked above

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-ui</artifactId>
    <version>last.version</version>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot</artifactId>
    <version>2.1.11.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-autoconfigure</artifactId>
    <version>2.1.11.RELEASE</version>
</dependency>

My Spring mvc project already has servlet context configuration so I assumed I only need to register/import open api and swagger configuration files.

So I did the following

@EnableMvc
@Configuration
@import({org.springdoc.ui.SwaggerConfig.class,
                org.springdoc.core.SwaggerUiConfigProperties.class, org.springdoc.core.SwaggerUiOAuthProperties.class,
                org.springdoc.webmvc.core.SpringDocWebMvcConfiguration.class,
                org.springdoc.webmvc.core.MultipleOpenApiSupportConfiguration.class,
                org.springdoc.core.SpringDocConfiguration.class, org.springdoc.core.SpringDocConfigProperties.class,
                org.springframework.boot.autoconfigure.jackson.JacksonAutoConfiguration.class

 @Bean
Public OpenAPI(){
return new OpenAPI();
}

When I run my application I gets the following error

“Java.lang.NoSuchMethodError:org.springframework.core.type.AnnotatgedTypeMetadata.getAnnotations()/Lorg/springframework/core/annotations/MergeAnnotations”
