flyway exception, detected failed migration

Question

I've got a Flyway exception:

FlywayException: Detected failed migration to version 1.0

I looked for on documentation and forums but I didn't found what mean this exception. Please someone can tell me what can be the reasons of these exception ! Thanks

Solution 1

"FlywayException: Detected failed migration to version 1.0"

it means that you ran migrate before and it failed at 1.0 for some reason. You need to identify why the previous migration failed at 1.0 and solve it if you have already not done so. Once solved you need to run flyway repair to tell flyway that whatever failed is now out of the way.

Then run flyway migrate again. If it fails again, you are back on step 1. Good luck with the migration.

Solution 2

Make

select * from your_database_name.flyway_schema_history

you will get something like this:

Query to flyway_schema_history table

Then find the entry that corresponds to the migration that is failing and delete it, it should work.
