I’ve created a custom datatype according to the documentation (YearDatatype of the example Data Types :: Jmix Documentation), but now at every liquibase changelog generation, it always generates a new xml changelog file with the same content:
<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog
xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-4.11.xsd"
objectQuotingStrategy="QUOTE_ONLY_RESERVED_WORDS">
<changeSet id="1" author="rds">
<modifyDataType columnName="YEAR" newDataType="integer" tableName="RDS_SALES"/>
</changeSet>
</databaseChangeLog>
applying the changelog does not make any difference
