이 부분을 정하고, 구글 신의 도움을 청했다.

해결

문제의 원인은 사용하려던 spring.fox 2.9.2 version에는 org.springframework.plugin.core.Plugin이 removed 되어 발생한 오류였다.

하여 해당 버전을 snapshot으로 변경하였다.

pom.xml에 dependency와 repository를 추가해주었다.

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger2</artifactId>
  <version>3.0.0-SNAPSHOT</version>
</dependency>

<repositories>
  <repository>
    <id>jcenter-snapshots</id>
    <name>jcenter</name>
    <url>http://oss.jfrog.org/artifactory/oss-snapshot-local/</url>
  </repository>
</repositories>

하여 문제 없이 잘 실행되었다!

오늘도 해결 :) 🌟
