Error on integration of liquibase with Spring Boot 2

Question

I am working on a Spring Boot project, and i am asked to call a sql file using liquibase.

The sql file contains scripts for Spring Quartz tables configuration.

Here is the POM file:

Answer 1

To add to the @SteveDonie's answer:

You can solve this error by:

• adding <validCheckSum>7:18262c5c5851874dff0c954d60b47d59</validCheckSum> to your changeSet.
• adding <validCheckSum>ANY</validCheckSum> to your changeSet.
• change the id of your changeSet.
• removing the record about this changeset in databasechangelog table (I wouldn't recomend this).
• drop your database and then recreate it from your liquibase changeSets.

Answer 2

The error message isn't that clear if you haven't used Liquibase much.

This message:

15:44:39.081 [localhost-startStop-1] ERROR org.springframework.boot.SpringApplication - Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'liquibase' defined in class path resource [org/springframework/boot/autoconfigure/liquibase/LiquibaseAutoConfiguration$LiquibaseConfiguration.class]: Invocation of init method failed; nested exception is liquibase.exception.ValidationFailedException: Validation Failed:
 1 change sets check sum
      classpath:/db/changelog/db.changelog-master.yaml::2::marouane is now: 7:18262c5c5851874dff0c954d60b47d59

is the key error. When Liquibase applies a changeset to a database, it computes a checksum of the changeset at that exact moment and save the checksum into the database in the DATABASECHANGELOG table. If someone then alters the changeset and then attempts to use Liquibase to update the database, Liquibase will compute a different checksum for that changeset and let you know that there is a difference.

There are at least two ways to 'solve' this problem.

1. If you know that the database can be altered (maybe it is a dev instance) and you also know that the changeset as it exists is correct, then you can just drop the database and re-create it from the changelog.

2. If the changelog (or the file(s) that it refers to) was changed in error, the thing to do is revert the changelog to what is was before. If the changelog was changed by editing a changeset (or changing a file like sql/tables_mysql.sql), that is incorrect - once a changeset has been applied to ANY database, the correct way to make a change to whatever the changeset was altering is to create another changeset.

You didn't specify what was in the file sql/tables_mysql.sql but the contents of that file are also used in the checksum process, so when that changes, you will also see this error.
