Flyway is not executing script - spring-boot

Question

I have Spring Boot application with Flyway.
I have following sql script:
src/main/resources/db/migration/V1__init.sql
but the script is not executed.
In application.properties file I have:
spring.datasource.url = jdbc:mysql://localhost:3306/carorderprocess?useSSL=false
spring.datasource.username = root
spring.datasource.password = ...
spring.flyway.baselineOnMigrate = true
When I run application, in DB I only see:
mysql> select * from flyway_schema_history;
+----------------+---------+-----------------------+----------+-----------------------+----------+--------------+---------------------+----------------+---------+
| installed_rank | version | description | type | script | checksum | installed_by | installed_on | execution_time | success |
+----------------+---------+-----------------------+----------+-----------------------+----------+--------------+---------------------+----------------+---------+
| 1 | 1 | << Flyway Baseline >> | BASELINE | << Flyway Baseline >> | NULL | root | 2019-11-19 10:47:52 | 0 | 1 |
+----------------+---------+-----------------------+----------+-----------------------+----------+--------------+---------------------+----------------+---------+
So the script is not executed, why?

Answer 1

This script won't run, as the version of the filename provided is not higher than the greatest version stored in flyway_schema_history table. There are two solutions you can do:
Clear the flyway_schema_history table
Rename your file to V2__init.sql (recommended solution)
Then simply restart your spring boot app, and changes should be applied out of the box
One note: 1st solution probably requires removal of spring.flyway.baselineOnMigrate = true property. I would also consider if you really need it. What it does can be found here

Answer 2

When you create Spring Boot application using Flyway, you need to do the next steps:
First. Add flyway dependency in pom.xml, if using maven:
<plugin>
<groupId>org.flywaydb</groupId>
<artifactId>flyway-maven-plugin</artifactId>
<version>4.0.3</version>
</plugin>
Second. Generate flyway.properties file and it should reside in the same directory as the pom.xml file. Default configs to describe:
flyway.user=databaseUser
flyway.password=databasePassword
flyway.schemas=schemaName
flyway.url=jdbc:h2:mem:DATABAS
flyway.locations=filesystem:db/migration
Third. Create your migration files under db/migration folder. For example - V1_1_0__my_first_migration.sql.
Fourth. Run the application: mvn spring-boot:run.
