导入org.hibernate无法解析

当尝试从 org.hibernate 进行任何导入时，会抛出错误The import org.hibernate cannot be resolved

例如，以下所有导入都不起作用：

import org.hibernate.SessionFactory;
import org.hibernate.boot.Metadata;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;

我正在使用 Hibernate 版本 6.1.3.FINAL。

我在 Eclipse 中工作。

我尝试下载 Hibernate 版本 6.0.0.CR2 （我找不到更新的版本）并将其添加到项目中Build Path > Configure Build Path > Libraries > Classpath > Add external JARs

我尝试将项目中的Java版本从20更改为17，调用Clean，调用Maven > Update Project- 没有任何效果。
