Please read liquibase usage for instructions to automatically generate changesets. After you generated a changeset do not forget to add it to git and in src/resource/db/changelog/db.changelog-master.yml
The old way to automatically generate the sql schema file (directly using hibernate) can still be used for debugging. Use the following command:
mvn package -DskipTests && rm -f src/main/resources/timeseries.sql && java -jar target/gridsuite-timeseries-server-1.0.0-SNAPSHOT-exec.jar --spring.jpa.properties.jakarta.persistence.schema-generation.scripts.action=create
