Liquibase-Hibernate：如何从 Spring-Boot JPA 实体生成变更日志？
Liquibase-Hibernate: How to generate changelog from Spring-Boot JPA entities?
我在从 Spring-Boot 项目的 JPA 实体生成初始变更日志时遇到问题。
我的pom.xml如下：

显然更新日志是正确生成的，因为它显示了计算的校验和，但它最终在
处失败了
Caused by: java.lang.NullPointerException
at liquibase.snapshot.jvm.JdbcSnapshotGenerator.getDatabaseCatalogNames (JdbcSnapshotGenerator.java:147)
我该如何解决这个问题，让它根据 JPA 实体生成更新日志，而无需使用真实的数据库？
更新

liquibase.properties文件如下：
changeLogFile=src/main/resources/database/liquibase/isolated/master.xml
outputChangeLogFile=src/main/resources/database/liquibase/isolated/init.xml

现在，运行 命令 mvn liquibase:generateChangeLog 正确地在 init.xml 文件中生成初始变更日志。

下面是 liquibase.properties 文件：

当我运行命令
mvn liquibase:generateChangeLog -X
在数据库 [Full log on Pastebin]:

显然更新日志是正确生成的，因为它显示了计算的校验和，但它最终在
处失败了Caused by: java.lang.NullPointerException
at liquibase.snapshot.jvm.JdbcSnapshotGenerator.getDatabaseCatalogNames (JdbcSnapshotGenerator.java:147)
我该如何解决这个问题，让它根据 JPA 实体生成更新日志，而无需使用真实的数据库？
更新

终于通过将 Bean Validation API & Javassist 依赖项添加到 liquibase 插件使其工作。

liquibase.properties文件如下：
changeLogFile=src/main/resources/database/liquibase/isolated/master.xml
outputChangeLogFile=src/main/resources/database/liquibase/isolated/init.xml
url=hibernate:spring:eu.project.organization.domain.isolated?dialect=liquibase.ext.hibernate.database.HibernateGenericDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy
driver=liquibase.ext.hibernate.database.connection.HibernateDriver
现在，运行 命令 mvn liquibase:generateChangeLog 正确地在 init.xml 文件中生成初始变更日志。
