Actually, the rollback tag isn't empty, it is referencing a
changelog. That is telling liquibase that to rollback changeSet
"test-1111-rollback"
you execute what is in "test-1111" which creates the table.
Steve's
answer is still correct, though. You don't need the
test-1111-rollback changeSet at all. Take it out and Liquibase
automatically knows how to rollback test-1111 if you ask it to.
