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.webmvc.config.RepositoryRestMvcConfiguration.backendIdConverterRegistry(RepositoryRestMvcConfiguration.java:721)
The following method did not exist:
org.springframework.plugin.core.PluginRegistry.of(Ljava/util/List;)Lorg/springframework/plugin/core/PluginRegistry;
The method's class, org.springframework.plugin.core.PluginRegistry, is available from the following locations:
jar:file:/home/nmigeo/.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/nmigeo/.m2/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
从我在错误描述中看到的情况来看，/home/nmigeo/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar 似乎被加载了两次。这就是问题所在。
除此之外，这是我在 pom.xml 中的依赖项，尽管我仔细检查了它们并且我没有任何重复的依赖项，根据其他 Whosebug 帖子，这可能是错误的来源。

导致错误的原因是什么？作为未来的参考，在尝试调试此类错误时我应该采取哪些步骤？非常感谢。
编辑：
错误说要检查我的类路径，但因为我在 eclipse 上生成了 spring 引导项目，所以我觉得那不是错误
编辑 2：
添加了整个 pom.xml 而不仅仅是依赖项
您使用的 spring-plugin-core 版本与您使用的 Spring Data REST 版本不兼容。 Spring Boot 2.2 使用 Spring Data REST 3.2 需要 spring-plugin-core 2.0.
当 Maven 在依赖树中多次遇到相同的依赖时，最接近树根的依赖版本将获胜。您可以 运行 mvn dependency:tree 查看树。如果这样做，您会看到 spring-plugin-core 被列为 io.springfox:springfox-swagger2 的依赖项并且它使用的是版本 1.2.0.
如果要使用 Spring Data REST，则需要使用 2.0。添加你自己对版本 2.0.0.RELEASE 的 spring-plugin-core 的依赖就可以了。但是，我相信它也会破坏 Springfox，因为它还不兼容。请参阅 this issue 了解更多详细信息。
简而言之，您可以使用 Spring Boot 2.1.x 并使用 Springfox 或者您可以使用 Spring Boot 2.2.x但在他们有机会恢复兼容性并发布新版本之前，您必须停止使用 Springfox。
这是我的第一个 Spring 启动应用程序，在将其安装到 运行 时遇到了一些问题。我不明白我做错了什么。

Action:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.plugin.core.PluginRegistry
从我在错误描述中看到的情况来看，/home/nmigeo/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar 似乎被加载了两次。这就是问题所在。
除此之外，这是我在 pom.xml 中的依赖项，尽管我仔细检查了它们并且我没有任何重复的依赖项，根据其他 Whosebug 帖子，这可能是错误的来源。

导致错误的原因是什么？作为未来的参考，在尝试调试此类错误时我应该采取哪些步骤？非常感谢。
编辑： 错误说要检查我的类路径，但因为我在 eclipse 上生成了 spring 引导项目，所以我觉得那不是错误
编辑 2： 添加了整个 pom.xml 而不仅仅是依赖项
您使用的 spring-plugin-core 版本与您使用的 Spring Data REST 版本不兼容。 Spring Boot 2.2 使用 Spring Data REST 3.2 需要 spring-plugin-core 2.0.
当 Maven 在依赖树中多次遇到相同的依赖时，最接近树根的依赖版本将获胜。您可以 运行 mvn dependency:tree 查看树。如果这样做，您会看到 spring-plugin-core 被列为 io.springfox:springfox-swagger2 的依赖项并且它使用的是版本 1.2.0.
如果要使用 Spring Data REST，则需要使用 2.0。添加你自己对版本 2.0.0.RELEASE 的 spring-plugin-core 的依赖就可以了。但是，我相信它也会破坏 Springfox，因为它还不兼容。请参阅 this issue 了解更多详细信息。
简而言之，您可以使用 Spring Boot 2.1.x 并使用 Springfox 或者您可以使用 Spring Boot 2.2.x但在他们有机会恢复兼容性并发布新版本之前，您必须停止使用 Springfox。
