mvn liquibase:generateChangeLog not working with an URL problem - spring

Question

I don't understand something with Liquibase and Spring Boot.
When I run my spring boot project with : mvn spring-boot:run
My changelog-v1.0.xml create a table and add two users inside my table user. So my liquibase is linked to my mySQL Database with success. But ... I don't know why, I can't used mvn liquibase command without failure.
Exemple, I want to save my database using :
mvn liquibase:generateChangeLog
But I have that log failure :
Failed to execute goal org.liquibase:liquibase-maven-plugin:4.9.0:generateChangeLog (default-cli) on project demo: The database URL has not been specified either as a parameter or in a properties file.
I think, when i'm using the command line, he don't use my configuration inside pox.xml but I don't know how to do that.
# pom.xml
<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>4.9.0</version>
<configuration>
<propertyFileWillOverride>true</propertyFileWillOverride>
<promptOnNonLocalDatabase>false</promptOnNonLocalDatabase>
<ChangeLogFile>src/main/resources/db/changelog/changelog-master.xml</ChangeLogFile>
<driver>${spring.datasource.driverClassName}</driver>
<url>${spring.datasource.url}</url>
<username>${spring.datasource.username}</username>
<password>${spring.datasource.password}</password>
</configuration>
<dependencies>
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>
</dependencies>
</plugin>
My pom.xml is correctly setup because new changelog file inside liquibase directory create or update my data from my mysql database.

mvn liquibase:generateChangeLog does not depend on spring, so it is not going to read the spring file. You can either create a liquibase.properties file and reference it.
I changed the pom to reference a properties file
https://docs.liquibase.com/tools-integrations/maven/maven-pom-file.html
and then changed the changeLogFile configuration to use outputChangeLogFile like this:
<outputChangeLogFile>src/main/resources/db/changelog/changelog-master.xml</outputChangeLogFile>
