Command I have used:

liquibase --url=mongodb://XXXXX/test?authSource=admin --changeLogFile=“changeset\_master.xml” update

Error;

ERROR: Exception Details  
ERROR: Exception Primary Class: DatabaseException  
ERROR: Exception Primary Reason: liquibase-mongodb extension cannot execute changeset  
Unknown type: liquibase.statement.core.CreateTableStatement  
Please check the following common causes:

- Verify change set definitions for common error such as: changeType name, changeSet attributes spelling (such as runWith, context, etc.), and punctuation.
- Verify that changesets have all the required changeset attributes and do not have invalid attributes for the designated change type.
- Double-check to make sure your basic setup includes all needed extensions in your Java classpath
