liquibase does not generate table DATABASECHANGELOG

Question

I'm new to liquibase and I want to use it on an database in production. It's a small application, but instead of creating schema by hand I would like to use something more professional like liquibase.

What I plan to do is to make a changelog between the current schema in production and the new schema ready for the new application. I've followed many tutorials but there is still something missing. The output changelog.xml always imports all the schema and doesn't make the difference with the existing. I saw that liquibase had to create the table DATABASECHANGELOG but I couldn't see them on my computer.

What I did :

• dump of the current db in production and import on dev computer
• from core project added liquibase.properties and launched the following command : mvn clean resources:resources liquibase:generateChangeLog
• this generated a master.xml with all the schema, but didn't create the tables DATABASECHANGELOG in DB (the table DATABASECHANGELOGLOCK was created when commenting outputChangeLogFile, and the LOCKED value is 0)
• created manually the DATABASECHANGELOG from http://www.liquibase.org/databases.html
• rerun the command mvn liquibase:generateChangeLog. Still nothing

pom.xml :

liquibase.properties :

url=jdbc:mysql://localhost:3306/my_db
username=user
password=pass
driver=com.mysql.jdbc.Driver
outputChangeLogFile=src/main/resources/liquibase/master.xml

NB : commenting outputChangeLogFile made liquibase create the table DATABASECHANGELOGLOCK, but only this one.

As far as I know (I'm new too), tables DATABASECHAGELOG and DATABASECHANGELOGLOCK are created by update option: mvn liquibase:update
