Maven Properties
You can set Liquibase Maven properties to change the behavior of your commands. You can pass arguments, like changelog-file, in Maven in the following ways:
Directly in your pom.xml file.
In a liquibase.properties file referenced in your POM.
As environment variables.
As JVM system properties.
Tags like expressionVariables, expressionVars, and systemProperties can only be set in your POM.
For a list of properties you can set, see the property tables on pages for individual Maven Goals.
Note: You can also run the Maven help goal: mvn liquibase: help -Ddetail=true.
Syntax
Directly in your POM
The <configuration> section of the POM, within the <plugin> section for Liquibase, allows you to specify settings that Liquibase will use when it runs. The settings control Liquibase's behavior by specifying the attributes Liquibase uses during execution. For example:
<configuration>
<changeLogFile>changelog.xml</changeLogFile>
<url>MyJDBCConnection</url>
<username>dbuser</username>
<password>dbpassword</password>
</configuration>
Referencing the liquibase.properties file
Note: If you use liquibase.properties or a custom Liquibase properties file, it must be located in the src/main/resources directory or another place in the search path.
<configuration>
<propertyFile>liquibase.properties</propertyFile>
</configuration>
Then, in your liquibase.properties file, specify the properties as follows:
changeLogFile=changelog.xml
url=MyJDBCConnection
username=dbuser
password=dbpassword
For more information, see Create and Configure a liquibase.properties File.
Full pom.xml example
Depending on your project and the Maven goals you want to run, you might need a specific pom.xml configuration. The following is a basic example of how you can implement it and where the <plugin> tag can typically appear inside the overall structure.
Note: You can add another section, modify the existing ones, and configure them in your own way. For more information, see Using Liquibase and your Maven POM File.
