How to run Flyway commands in spring boot application?

I've been using flyway to handle my sql scripts migrations and am very happy with it. However, when I decided to move forward with spring boot and flyway I have stuck when I tried to run the different flyway commands from the app.

When I run my fat jar app, the migrate flyway command is automatically executed. All went well until one of the scripts failed in a linux (because of the case sensitive). So, when I wanted to execute the repair command I had no way to do it, so I had to manually remove the entry in the schema_version table.

So, my question is that if it is even possible to other flyway commands through the app without creating a custom flyway handler and just using its native integration.

I didn't find any spring boot property for command or something like this.

Any help?

There's no command property for Flyway integration. If you want you can implement your own FlywayMigrationStrategy, which is a one method interface:

public interface FlywayMigrationStrategy {

    /**
     * Trigger flyway migration.
     * @param flyway the flyway instance
     */
    void migrate(Flyway flyway);

}

You can pick up for instance a command line argument that you pass and do repair instead of migrate:

void migrate(Flyway flyway) {
    String command = env.getProperty("flyway.commamd", "migrate");
    switch (command) {
     case "migrate":
         flyway.migrate();
         break;
     case "repair":
         flyway.repair();
         break;
     default:
         throw new IllegalArgumentException("Invalid command: " + command);
 }
}
