Read liquibase change log properties from external property file with maven - liquibase

Question

I want to read Liquibase change log properties from an external property file. I do not want to define them in the databasechangelog.xml in property tag as I want different parameters for different environments. My external property file will be chosen according to the profile I chose for the maven plugin.
E.g. CREATE OR REPLACE SYNONYM ${schema1}.myTable FOR ${schema2}.myTable;
I want these parameters ${schema1} and ${schema2} to picked from an property file. Is this possible
Edit: According to #bilak comment I tried this
pom.xml:
<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>3.4.2</version>
<configuration>
<propertyFile>${basedir}/../environments/${build.profile.id}/liquibase.properties</propertyFile>
<changeLogFile>${basedir}/src/main/resources/sql/db-changelog-master.xml</changeLogFile>
</configuration>
</plugin>
liquibase.properties:
driver=oracle.jdbc.OracleDriver<br>
url=xxxxx<br>
username=xxxxxx<br>
password=xxxxxx<br>
parameter.testcolumn=test_column
db config parameters are read correctly but parameter.testcolumn is not used
mvn liquibase:update -Pprofile

You can use file liquibase.properties (default name) and put there variables like:
parameter.schema1=yourSchema1
parameter.schema2=yourSchema2
edit:
That option doesn't work with liquibase-maven-plugin but there could be workaround with maven-exec-plugin:
<profiles>
<profile>
<id>liquibase</id>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<configuration>
<executable>java</executable>
<arguments>
<argument>-classpath</argument>
<classpath/>
<argument>liquibase.integration.commandline.Main</argument>
<argument>--defaultsFile=src/main/resources/database/liquibase.properties</argument>
<argument>updateSQL</argument>
</arguments>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
if you execute then mvn exec:exec -Pliquibase it should replace your placeholders with parameters from liquibase.properties.
