Hibernate liquibase.exception.DatabaseException:java.lang.ClassNotFoundException

我是Liquibase和JHipster的新手，在使用maven插件生成差异时遇到了一些问题

运行

mvn liquibase时，我遇到以下错误：diff-e-X

我的pom的相关部分是：

问题是您在

liquibase maven插件

配置的内部将

方言

属性留空。插件，当然，失败了。到实现用于Hibernate的自定义方言的类

<referenceUrl>hibernate:spring:com.myapp.domain?dialect=&amp;hibernate.ejb.naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringNamingStrategy</referenceUrl>
<!--                                            ^^^^^^^^ -->

在插件依赖项中，您还依赖于Hibernate的冲突版本：

liquibase-hibernate4

，但您依赖于Hibernate Core 5.2.1.Final和。因此，您需要删除对

hibernate core

@Magick的依赖关系，这是由hibernate版本冲突引起的另一个错误。最好发布一个与此相关的新问题，因为它实际上是不相关的。在这个新问题中，请务必发布Liquibase和Hibernate的确切版本。由于Liquibase本身依赖于hibernate 4，因此我将尝试删除对

hibernate核心的依赖。
<referenceUrl>hibernate:spring:com.myapp.domain?dialect=&amp;hibernate.ejb.naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringNamingStrategy</referenceUrl>
<!--                                            ^^^^^^^^ -->

<referenceUrl>hibernate:spring:com.myapp.domain?dialect=org.hibernate.dialect.PostgreSQL94Dialect&amp;hibernate.ejb.naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringNamingStrategy</referenceUrl>
