springboot spring-plugin异常的解决办法

在学习ES的过程中，本着有最新就用最新的想法，使用了springboot2.3.x的版本，在实操过程中遇到了配置和方法过时的情况，于是将springboot版本降级为2.1.13，诡异的事情发生了，原本能正常启动的项目起不来了，报错如下：

***************************
APPLICATION FAILED TO START
***************************

Description:

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

    springfox.documentation.schema.plugins.SchemaPluginsManager.viewProvider(SchemaPluginsManager.java:95)

The following method did not exist:

    org.springframework.plugin.core.PluginRegistry.getPluginFor(Ljava/lang/Object;)Ljava/util/Optional;

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

    jar:file:/D:/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:/D:/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.plugin.core.PluginRegistry

百度了一下问题，遇到了类似问题的帖子，就试了试

一开始使用了1.2.0的版本，但是问题依旧存在，又把帖子往下划拉了划拉，试了试2.0.0版本的，嘿，还真好使了

问题原因：版本冲突

<dependency>
    <groupId>org.springframework.plugin</groupId>
    <artifactId>spring-plugin-core</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.plugin</groupId>
    <artifactId>spring-plugin-metadata</artifactId>
