当我在默认运行模式下启动spring boot应用程序时，它会正常执行liquibase语句。
再次停止并再次运行会正常跳过变更集，因为它已经执行了。
从调试模式开始，但是尝试再次执行变更集，即使它已经运行了。
我把它转过来并首先在debug中执行了更改，它在databasechangelog中整齐地创建了条目 当在非调试模式下第二次运行时，同样的情况发生
我的更改是本机sql格式，数据库是带有mysql连接器的mariadb
我比较了两个databasechangelog（先运行vs先调试）条目的md5总和，它们是相同的。
liquibase版本是3.5.4我也测试了3.5.5，结果相同
mysql Ver 15.1使用readline 5.2分发10.0.34-MariaDB，用于debian-linux-gnu（x86_64）
这里也是liquibase失败的记录部分
