Thanks a lot for your answer.
I removed the diffChangelogFile parameter, then the output show the
two db is same. But in fact, the two db is different.
In the same time, it shows correct diff information by using the “liquibase diff” in command line with same configuration.
So I think the issue is not diffChangeLogFile parameter, it is just
“mvn liquibase:diff” issue.
“liquibase diff” in command line
