How Liquibase Finds Files: Liquibase Search Path
https://docs.liquibase.com/concepts/changelogs/how-liquibase-finds-files.html
For example, if your referenced file path is project1/db.changelog.xml
and your search path is /Users/example/liquibase,/projects/global
, Liquibase will look for /Users/example/liquibase/project1/db.changelog.xml
and /projects/global/project1/db.changelog.xml
.
