Offline UpdateSQL for mariadb with csv doesn't handle boolean values correctly ?

Description

I use maven liquibase plugin to generate SQL from changeset for mariadb. A couple of changesets use loadUpdateData with csv data as input. The table I try to update contains boolean values, which are declared as 'bit' in mariadb. The CSV I have contains 'true' or 'false' value for values for these columns. When I generate the SQL in offline mode with mvn liquibase:updateSQL, I get insert statement with 'true' or 'false' values instead of 1 or 0.

I had a look at stackoverflow where they say that I should add a column element with valueBoolean="true", but it doesn’t change anything in the offline mode I’m in: I still get 'true' or 'false' values for bit column, which are incorrect values.

<loadData encoding="UTF-8"
          file="path/to/file.csv"
          separator=","
          tableName="MY_TABLE">
    <!-- specify that values in my_boolean_column should be interpreted as Boolean values -->
    <column name="my_boolean_column" type="BOOLEAN" />
</loadData>

<plugin>
                <groupId>org.liquibase</groupId>
                <artifactId>liquibase-maven-plugin</artifactId>
                <configuration>
                    <changeLogFile>${liquibase.dir}/changelog-master.xml</changeLogFile>
                    <url>offline:mariadb?outputLiquibaseSql=true&amp;changeLogFile=${liquibase.offline.dir}/databasechangelog.csv</url>
                    <migrationSqlOutputFile>${liquibase.offline.dir}/upgrade-toto-${project.version}.sql</migrationSqlOutputFile>
                </configuration>
            </plugin>

Thank you for your help 😃

After searching more and investigating, I found that this was not a bug but a problem between the keyboard and the chair. I did not mention the mapping column in the loadupdatedata with a correct type that should be in the list https://www.liquibase.org/javadoc/liquibase/change/core/LoadDataChange.LOAD_DATA_TYPE.html
