Answer 1

Cannot find migrations location in: [classpath:db/migration]
Either add the appropriate migrations, or if they're in the right place, check their namings.
Proper location for your migrations, i.e. the classpath:db/migration, is src\main\resources\db\migrations folder.
Proper naming logic can be found here.

Answer 2

the error log description "Cannot find migrations location in: [classpath:db/migration] (please add migrations or check your Flyway configuration)" plz show more information about Flyway configuration

Answer 3

I assume you don't have any flyway migrations just yet, if so you can remove flyway dependency from gradle or maven for now, it should help to start the application.
If you decide that you want to have migrations then add flyway back, and create folder called db/migrations in your classpath, and add a migration file there.
