回答1:

You need to include the new changelog file in your src/main/resources/config/liquibase/master.xml file.

<include file="classpath:config/liquibase/changelog/my_new_changelog.xml" 
    relativeToChangelogFile="false"/>

Next time you run the app, changes will be applied.

You can also update the database with the following maven task : mvn liquibase:update.

Here is the doc about using jhipster in development.

I created a file on

src/main/resources/config/liquibase

Ex:

<?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-3.4.xsd">

<changeSet author="lazaro" id="altertable-02">
    <addColumn catalogName="mySchema"
            schemaName="public"
            tableName="myTableName">
        <column name="atributeName" type="bigint"/>
    </addColumn>
</changeSet>

And added on

src/main/resources/config/liquibase/master.xml

A include tag:

<include file="classpath:config/liquibase/changelog/add_column_quantity_entity_Item.xml" relativeToChangelogFile="false"/>
