custom properties in liquibase.properties file - liquibase

Question

I am using liquibase 2.0.5 and my properties file looks like below
#liquibase.properties
url=jdbc:oracle:thin:#//localhost:1521/orcl
username=myschama
password=myschama
masterUsername=system
masterPassword=system
I want to use system user to create myschema user. Currently, I get the following error.
Unexpected error running Liquibase: Unknown parameter: 'masterUsername'
SEVERE 12/21/17 12:59 PM:liquibase: Unexpected error running Liquibase: Unknown parameter: 'masterUsername'
liquibase.exception.CommandLineParsingException: Unknown parameter: 'masterUsername'
at liquibase.integration.commandline.Main.parsePropertiesFile(Main.java:387)
at liquibase.integration.commandline.Main.main(Main.java:122)
Is it possible to have such custom values in the properties file

Answer 1

If you want to use it in your changeSets as property, e.g.
<changeSet ...>
<sql>
INSERT INTO myTab(some_column) VALUES ('${masterUsername}')
</sql>
</changeSet>
then try putting this into your liquibase.properties:
parameter.masterUsername=your_desired_value
As an alternative, you can pass these on the command line as Java properties, e.g.
liquibase update ... -DmasterUsername=your_desired_value
See http://www.liquibase.org/documentation/changelog_parameters.html and http://www.liquibase.org/documentation/command_line.html for details.
