    Description:

    An attempt was made to call a method that does not exist. The
    attempt was made from the following location:

        org.springframework.data.rest.core.support.UnwrappingRepositoryInvokerFactory.<init>(UnwrappingRepositoryInvokerFactory.java:57)

    The following method did not exist:

        'org.springframework.plugin.core.PluginRegistry org.springframework.plugin.core.PluginRegistry.of(java.util.List)'

    The method's class, org.springframework.plugin.core.PluginRegistry,
    is available from the following locations:

        jar:file:/home/md7zn4/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar!/org/springframework/plugin/core/PluginRegistry.class

    It was loaded from the following location:

        file:/home/md7zn4/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar

    Correct the classpath of your application so that it contains a
    single, compatible version of

Fixed Version

Springboot + HATEOAS 프로젝트에서 스프링부트 버전업에 따라 그레들, 스웨거도 Swagger3으로 생각없이 버전업에 따라 에러 발생한 것으로 아래와 같이 버전 맞춤
Swagger2 시에 404 not found error 시에도 아래와 같이 해결이 될 수 있음.

본인 프로젝트가 Springboot 인지 Spring 프로젝트 기반인지 WebMvc 등 의존성 주입에 따라 해결 방법이 상이하므로 해당 포스팅 참고해서 먼저 확인하고 에러 해결.
