How to incrementally update changelog?

Question

I've generated changelog with

java -jar liquibase.jar --changeLogFile="./data/<insert file name>" generateChangeLog

I've got a "create table" changelog.

After it I altered table by adding a new column and runned

java -jar liquibase.jar --changeLogFile="./data/<insert file name>"

generateChangeLog

again. I expected to see incremental log with "create table" and "alter table", but it showing "ChangeLog ...... already exists!".

How to incrementally update ChangeLog?

Thank you!

The generateChangelog command is used to generate an initial changelog. If you want to append to a changelog you use the diffChangelog command.
