Liquibase coming with Spring Boot handles the database well with changelog.xml. How can it generate its sql at the same time?

I’m using the default Liquibase configuration coming with Spring Boot.

I have:

• a changelog.xml file in src/main/resources/db/changelog that works fine,
• along with url, changeLogFile, driver, username, password properties in application.properties,
• and a Maven pom.xml having this for <dependency> and <dependencyManagement>:

    <dependencies>
        ...

        <dependency>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-core</artifactId>
            <scope>runtime</scope>
        </dependency>
    </dependencies>

    <build>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.liquibase</groupId>
                    <artifactId>liquibase-maven-plugin</artifactId>

                    <configuration>
                        <promptOnNonLocalDatabase>true</promptOnNonLocalDatabase>
                        <propertyFile>${project.basedir}/../ApplicationMetierEtGestion/src/main/resources/application.properties</propertyFile>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

Aside from the update of the database structure led by changelog.xml that is working fine at development time, I would like Liquibase to generate also the related SQL files (by the mean of its updateSQL command).
This, because the next environments might not have Liquibase to handle the database updates.

How can I do that from here?

Answer

Liquibase has a goal that generates this SQL for you which is called updateSQL.
Have a look as it might be interesting in your case.
