Liquibase-Micronaut Workflow Demonstration

This sample application demonstrates how to setup a Micronaut application to use liquibase for managing database schemas reflected from GORM domain objects.

Step 1: start the application

Run the command: ./gradlew run

Notice that the application fails to start? This is because the database schema fails to validate because its missing tables required by the domain objects

Step 2: generate a change log

Run the command: ./generatechangelog.sh mydomainobject

This command generates a change log in the ./migrations directory. Inspect it to review the contents.

Step 3: update the master changelog

Edit ./migrations/changelog.groovy and uncomment the line include file: 'migrations/mydomainobject'

Step 4: migrate the database

Run the command ./migratelocaldb

The migration will successfully complete

Step 5: start the application

Run the command: ./gradlew run

The application should successfully start. Congratulations, you've migrated your development database.

To reset this example, delete the generatedb and developmentdb files created in the working directory.
