执行 mvn liquibase:diff 时出现问题，其中快照用作目标 url

Problem while executing mvn liquibase:diff where snapshot us used as target url

使用 liquibase 和 maven spring 引导项目在数据库的一种状态下生成了快照后来尝试使用 mvn liquibase:diff[= 生成快照和在线数据库之间的差异28=].

liquibase.properties如下

changeLogFile=src/main/resources/bd.changeLog-base.xml
diffChangeLogFile=src/main/resources/bd.changeLog-base.xml
outputChangeLogFile=src/main/resources/liquibase-new-changeLog.xml
url=offline:mysql?snapshot=src/main/resources/snap_shot.json
driver=com.mysql.jdbc.Driver

referenceDriver=com.mysql.jdbc.Driver
referenceUrl=jdbc:mysql://localhost:3306/db_sample
referenceUsername=yyyy
referencePassword=xxxx

在pom.xml

中使用以下maven插件依赖

请帮忙解决这个问题！

对我来说，通过将 liquibase-maven-plugin 从 3.5.5 版本升级到 3.10.1.

解决了这个问题
